A guide to image copyright and fair use images in 2026

Last updated — April 08, 2026

Copyright laws are a confusing territory, put in place to encourage creativity and protect both the rights of the owner and the public’s interest. With so many images available online, if your business works with them, and there are very few that don’t, it’s vital for you to know what you can and can’t use and to adhere to image copyright laws. More than that, you need to understand how to use images in a way that is respectful to the author’s ownership rights.

To help you avoid any unwanted legal disputes from copyright infringement, we’ve put together this guide so you can have a better understanding of what is right when it comes to image usage.

Key takeaways

• Most images online aren’t free to use, they’re automatically protected by copyright, even if there’s no visible notice.
• Fair use can apply, but it’s not a shortcut, instead, it’s a case-by-case judgment based on how and why the image is used.
• “Free” doesn’t always mean unrestricted, and most images still require attribution or limit commercial use.
• The more your team understands image rights, the easier it is to move faster, stay compliant, and avoid unnecessary risk in 2026.

Why fair use matters for images

Fair use isn’t just a creative loophole; it’s what allows marketers, designers, and content teams to create, critique, and communicate without constant permission barriers. For AEC marketers and creative teams, it assists with proposal visuals, thought leadership, and educational content while still respecting creators’ rights.

Why it matters now:

• Visual content dominates (over 65% of marketers say images are essential to storytelling)
• AI and remix culture are blurring ownership lines
• Copyright enforcement (and penalties) are increasing

Think of fair use as a risk-balancing framework, not a guarantee.

What is copyright as it relates to images?

Copyright protection begins the moment an image is created and fixed in a tangible form. That includes photographs, renderings, illustrations, and even certain AI-assisted works where human creativity plays a meaningful role.

In practice, this means that nearly every image you encounter online—from a construction site photo on LinkedIn to a rendering on a firm’s website—is automatically protected. The creator holds exclusive rights to reproduce, distribute, display, and adapt that image.

This default protection is why teams often run into risk: accessibility does not equal permission.

For content creators, these exclusive rights that govern their use and distribution ensure the owner can exercise a substantial amount of control over their work:

• They can reproduce the copyrighted work
• They can create derivative works based on the original, and
• They can display, perform, and distribute the work publicly

What copyright means for everyone other than the creator is that, in theory, they need to have express authorization to use a copyrighted work. However, there are legal constructs in place that allow copyrighted works to be seen and shared every day. If your business relies on images, then you need to know what you can use and understand the copyright rules for images.

The four factors of fair use

Fair use is determined using a four-factor test established in U.S. copyright law. Courts weigh all four together, so no one single factor determines the outcome. Here’s what they include.

Purpose and character of the use

Transformative uses—those that add new meaning, context, or purpose—are more likely to qualify as fair use.

Courts increasingly focus on whether your use changes the original image’s intent. For example, using a project photo to critique design decisions or explain engineering tradeoffs is more defensible than using that same image in a marketing brochure.

Recent case law, like Andy Warhol Found. for the Visual Arts, Inc. v. Goldsmith continues to emphasize “transformative use” as the most influential factor, particularly in commercial contexts.

Nature of the copyrighted work

Factual or published images are more likely to qualify for fair use than highly creative or unpublished works.

A photo documenting infrastructure conditions is treated differently than a highly stylized architectural photograph. The more creative and expressive the work, the stronger the protection.

Amount and substantiality of the portion taken

Using only what is necessary strengthens your case, but even small portions can infringe if they capture the core of the work. Courts evaluate both quantity and significance. Cropping or resizing an image doesn’t automatically reduce risk if the essential visual elements remain intact.

Effect of the use on the potential market

If your use could substitute for the original or reduce its value, it likely weighs against fair use.

This factor has become increasingly important in digital contexts. If your use removes the need to license or purchase the original image, it can undermine a fair use claim.

How long does image copyright last?

In most cases, copyright lasts for the creator’s lifetime plus 70 years.

For corporate or “work-for-hire” images, protection typically lasts 95 years from publication. After that, the image enters the public domain and can be used freely.

Understanding duration is critical for AEC firms working with legacy project photography, historical archives, or long-standing brand assets.

What’s changed in copyright and fair use in images for 2026?

Copyright law hasn’t been rewritten, but how it’s interpreted has shifted significantly due to technology.

Three trends are driving change:

• First, AI-related litigation is reshaping how courts think about authorship and transformation.
• Second, platform enforcement (on Instagram, TikTok, and LinkedIn) is becoming stricter, with automated detection and takedowns increasing.
• Third, commercial scrutiny is rising, meaning businesses face greater risk than individuals when relying on fair use.

Together, these changes mean one thing: fair use is still available, but the margin for error is shrinking.

Copyright and AI-generated images

Fully AI-generated images are generally not protected by copyright unless there is some type of meaningful human creative input involved.

In 2023–2025, the U.S. Copyright Office clarified that works generated solely by AI are not eligible for copyright protection. However, in a landmark decision, a human-authored image created with AI assistance (where the creator exercised clear control over composition and editing) was granted protection.

For marketers, this creates a nuanced reality:

• AI outputs aren’t automatically “free to use”
• Ownership depends on human involvement
• Training data controversies can introduce additional risk

So while AI simplifies creation, it definitely complicates ownership.

Copyright and user-generated content platforms

It’s important to know that publicly posted images on platforms like Instagram or TikTok are still copyrighted and can’not ‘t be freely reused.

Platform terms typically grant the platform a license, not other users. This means that downloading and reusing content (even with credit) can violate copyright.

Embedding content is sometimes safer because it preserves attribution and platform control, but even this approach is being debated in courts.

For AEC marketers sourcing project visuals from partners or clients, explicit permission is still always the safest route.

What are fair-use images?

Enforcing image copyright laws online is a complicated matter, as digital images are so easy to duplicate and reuse. It would be a huge undertaking if every image on the internet needed explicit authorization by the creator to not be in violation of image copyright rules. To counteract this, and to ensure that copyrighted works and the public’s interest are protected, fair use was created.

Fair use images are those that are acceptable for users to adopt and publish. Fair use grants limited use of copyrighted images without any prior authorization from the owner. Determining whether the use of an image adheres to fair use and understanding restrictions around its use, however, is a tricky matter. Fair use isn’t an outright approval to use the image as you wish; it is in place to provide limited use if it benefits the greater public. Copyright laws for images on the internet are complicated; fair use requires an understanding of the following factors:

• The image should be used for educational, nonprofit, reporting, or research purposes
• The image should be used as fact-based public content
• The image should only be used as a small, low-resolution version
• The image could not have been purchased or licensed

As you can see, fair use is complicated matter and doesn’t actually mean an image is free to use. If you are considering using an image under fair use, then you must understand the copyright rules that go with it.

How to apply the four factors to images

Applying fair use requires judgment, not checklists, so here’s a structured approach that can help.

Start by asking whether your use changes the meaning of the image. Then evaluate how much of the image you’re using, whether the original is highly creative, and whether your use could impact its market value.

If your use is commercial, non-transformative, and uses the full image, your risk increases significantly.

Examples of fair use

Understanding fair use is easier when you see how it plays out in real scenarios. The key thread across all fair use examples is that the image is being used to add insight, explanation, or critique, not just to enhance visual appeal.

Fair use commonly applies in situations where the image is essential to the point being made:

• Educational content explaining design or engineering concepts
• Blog posts comparing architectural styles or techniques
• Critiques of project outcomes or visual communication

For example, an AEC marketer writing a blog about façade performance might include a project photo with annotations highlighting material failures. In this case, the image acts as a vital part of the analysis.

In each of these scenarios, the image supports a new purpose, and that distinction is what strengthens a fair use argument.

Examples of uses that are likely not fair use

On the flip side, many common business use cases fall outside fair use, not because they’re malicious, but because they don’t meaningfully transform the original image. Instead, they reuse it for the same purpose it was created for: visual communication or promotion.

Uses that typically fall outside fair use include:

• Marketing materials, proposals, or sales collateral
• Reposting images without commentary or transformation
• Using images found via search engines without licensing

For instance, including a high-quality architectural photo in a proposal to make your firm appear experienced—where you didn’t design the project—is unlikely to qualify as fair use. The image is being used in the same meaning/format as the original owner intended: to market and persuade.

These uses are considered substitutive rather than transformative, meaning they can compete with the original creator’s ability to license and profit from their work, which is a complete no-go.

Image modification

Think that editing an image automatically makes it fair use?

It’s a common assumption that adding filters, cropping, or overlaying text creates something “new enough” to qualify as fair use. In reality, courts look for substantive transformation (a change in meaning, purpose, or message) not just visual tweaks.

For example, placing a color filter over an architectural photo and adding a headline for a marketing campaign doesn’t change the image’s core purpose, so that’s unlikely to qualify as fair use.

By contrast, using that same image in a technical article where you annotate structural issues, highlight design flaws, or compare materials introduces a new purpose: analysis. That kind of transformation is much more defensible.

The takeaway: if your edits don’t change why the image is being used, they likely don’t change your legal risk.

Thumbnail images

Thumbnails can qualify as fair use when used for indexing, search, or discovery purposes.

This principle comes from search engine cases (like Perfect 10 v. Amazon), where courts found that displaying small, low-resolution thumbnails served a new, functional purpose—helping users find information—rather than replacing the original image.

In practice, this means:

• A small preview image in a search result or internal DAM system is more likely to be fair use
• A clickable thumbnail that leads to the original source strengthens the argument

However, context still matters. If thumbnails are high-resolution, used in a commercial gallery, or eliminate the need to view the original image, they may no longer qualify as fair use.

The key distinction is whether the thumbnail acts as a pointer to the original, or a substitute for it.

Social media reposting

Are you giving credit to the original creator? Great. However, credit alone doesn’t make reposting legal.

One of the most common misconceptions in marketing is that attribution equals permission. In reality, copyright law does not recognize credit as a substitute for a license.

For example, resharing a project photo from another firm on LinkedIn or Instagram—even with a tag and full credit—can still infringe copyright if you don’t have permission. Again, the image is being reused for the same purpose it was created for: visibility and promotion.

There are safer alternatives:

• Use built-in platform sharing tools (like repost or embed features)
• Request explicit permission from the creator
• Use licensed or owned images instead

As platforms increase enforcement and creators become more protective of their work, relying on “credit only” is a high-risk strategy, especially for businesses.

How to legally use images online

Anyone using photos online has a responsibility to adhere to image copyright laws. It may seem an impossible task to understand fair use of photos and whether you are within your rights to use them. If you do decide to use a fair use image, you’ll need to consider why you’re using it, whether you’ve transformed it, and how much of it you’re using. If that all sounds like too much uncertainty and too much risk, then, fortunately, there are other ways to find images that you can use online.

There are three main options available to you, other than using fair use photos:

• Create your own images
• Download free stock photos
• Purchase stock photos

Ultimately, if there is any doubt as to whether you are correctly using a fair use photo or adhering to copyright rules, then sourcing an image in a different way is the best bet.

Licensed images

Licensed images from platforms like Getty Images or Shutterstock provide clear usage rights and remain the safest option for commercial work, especially proposals and marketing campaigns.

Public domain images

Public domain images, like those from U.S. government sources or expired copyrights, can be used without restriction. Resources like the Library of Congress and NASA provide high-quality options.

Creative commons images

Creative Commons licenses allow reuse under specific conditions. Some require attribution, while others restrict commercial use. Always verify the license type before using.

Fair use images

Fair use should be treated as a last resort, not a primary sourcing strategy, especially for business use. While fair use provides flexibility, it also introduces ambiguity. Unlike licensed or public domain images, fair use is not a predefined permission, it’s a legal defense that must be justified if challenged. That means the burden of proof falls on you, not the original creator.

For businesses, this risk is amplified. Commercial intent, brand visibility, and revenue impact all carry more weight in fair use evaluations, making outcomes less predictable and often less favorable than in educational or personal contexts.

A more sustainable approach is to prioritize licensed, owned, or clearly rights-free images, and use fair use selectively when the context genuinely supports it.

Where to find free images online in 2026

To avoid the confusion of fair use images and to be certain you’re on the right side of the copyright laws of images on the internet, the best places to search are storehouses of public domain images. These are images that photographers have contributed to the public domain, stating explicitly that users don’t need to seek permission for their use. Some of the most popular sites for sourcing free images are:

Source	License Type	Commercial Use	Attribution Required	Best For
Unsplash	Custom free license	Yes	No	High-quality marketing visuals
Pexels	Free license	Yes	No	Social and blog content
Pixabay	Free license	Yes	No	General-purpose imagery
Wikimedia Commons	Mixed	Varies	Often	Educational and historical content
Flickr (CC)	Creative Commons	Varies	Yes	Niche and archival imagery

Free vs. paid stock photo sites: Which should you use?

Paid stock photos are more reliable and legally secure; free stock is faster but carries more risk.

And while free platforms offer speed and accessibility, they often lack exclusivity and consistent quality. Overall, paid platforms provide clearer licensing, better curation, and lower legal risk, making them the better choice for client-facing work.

How businesses can ensure copyright compliance when using images

It’s vital for businesses not only to adhere to copyright rules for images but to protect the use of their image assets. Companies with extensive photo libraries and digital assets need to find a way to ensure security and to simplify license information. This is ever more important as the digital landscape evolves and copyright laws change.

For companies with extensive digital photos, managing them can be an extremely cumbersome process, leading to potentially costly errors. Implementing a Digital Asset Management (DAM) system can be a great way to manage your stock photo assets and ensure you stick to licensing terms and avoid any legal disputes. DAM systems allow you to control who uses your photos, how, when, and where.

Digital asset management allows businesses to create a central database of approved royalty-free images that can be easily searched and used across the organization. Compliant images can be tagged with relevant metadata, making them easier for users to find and understand any limitations in their use.

Whether your images are fair use, free stock photos, or created in-house, you need to make sure that they are used correctly. Everyone within an organization needs to follow copyright rules for images, and having a system in place to facilitate the correct usage of your image assets can reduce both the burden of management and the financial risk.
