How to Tell Whether You Have a CC BY compatible image license

Why a CC BY compatible image license matters

A CC BY compatible image license is one of the simplest checks you can make before placing someone else's image into your open access paper. If your article will be published under Creative Commons Attribution, every reused visual element needs to fit that licensing promise. That includes photos, icons, maps, diagrams, microscopy images, screenshots, and figure panels adapted from earlier work.

CC BY is generous, but it is not magic. It lets readers share and adapt your paper, including commercial reuse, as long as attribution is given. If one image inside the paper has a stricter license, the final article can become confusing or legally messy. Publishers may reject the figure, request replacement art, or ask for separate permissions.

The goal is not to become a copyright lawyer. The goal is to run a quick, sensible review before submission. When you know what to look for, most image license decisions take minutes, not hours.

What CC BY allows, in plain language

Creative Commons Attribution, usually written as CC BY, permits copying, redistribution, adaptation, and commercial use. The key condition is attribution. You must credit the creator, link to the license, and say whether changes were made.

The official Creative Commons CC BY 4.0 license page is the best source for the exact terms. For everyday publishing work, remember this: CC BY is broad. Any image you include must not stop readers from doing what CC BY says they can do with the article.

This is where many authors get tripped up. An image may be free to view, free to download, or free for educational use. None of those phrases automatically mean it works inside a CC BY paper. You need reuse rights that are at least as open as your article's license, or explicit permission that allows the same downstream uses.

Also note that attribution alone does not solve everything. Crediting an image is required, but credit is not permission. If the license forbids commercial use or adaptation, a perfect credit line will not make it compatible with a CC BY article.

CC BY compatible image license: the fast decision test

Use this quick test whenever you are unsure. First, identify the exact license attached to the image. Second, compare that license with the reuse rights your CC BY article grants. Third, check whether any extra terms block reuse, adaptation, or commercial use. Fourth, document the source and attribution before you forget where the image came from.

A CC BY compatible image license usually falls into one of three groups. It may be CC BY itself. It may be a more permissive license, such as CC0 or public domain status. Or it may be covered by written permission that explicitly allows reuse in a CC BY article, including redistribution and adaptation by readers.

Here is the practical rule: if the image license adds restrictions that CC BY does not have, treat it as incompatible unless you get separate permission. Common blockers include noncommercial terms, no derivatives terms, personal use only language, editorial use only language, and website terms that ban redistribution.

If the image is only a small element in a larger figure, the same logic still applies. A single restricted icon or photograph can create problems for the whole figure. We recommend replacing questionable components early, especially when you are building graphical abstracts, workflows, or summary diagrams.

A quick compatibility table for common licenses

The table below is a practical starting point. It does not replace publisher policy or legal advice, but it helps open access authors make faster decisions.

CC BY-SA deserves special care. Some publishers may allow unmodified CC BY-SA material with a clear credit line, while others avoid it in CC BY articles because ShareAlike adds a downstream licensing condition. If you are adapting the image, assume it is risky until your publisher confirms the approach.

Stock images are another trap. A paid download does not mean open licensing. Most stock platforms sell a limited license to you, not to every future reader of your CC BY paper. If readers cannot reuse the stock image under the same freedom as the article, it is not a clean fit.

Check the source, not just the label

License labels are useful, but sources matter. A random repost on a slide deck, social media account, or blog may claim an image is CC BY without having the right to license it. Try to trace the image back to the original creator, journal article, repository, museum, data archive, or institutional page.

When the source is a journal article, inspect the figure caption, article license, and any credit note. Some open access papers include third-party images that are excluded from the article license. You may see wording like, "not covered by the Creative Commons license" or "reproduced with permission." That warning means you cannot assume the image is reusable under CC BY.

When the source is a repository, look for item-level licensing. A collection may have one general policy, while individual files have different rights. This is common in museum databases, image archives, and research datasets. If the file page has no license, do not rely on a broad website statement unless it clearly applies.

When the source is an AI, design, or stock platform, read the export and use terms. Some tools allow publication but restrict resale, redistribution, or training data use. For a CC BY article, the safest assets are ones you made yourself, ones under CC BY or CC0, or ones with explicit open reuse terms.

Look for hidden restrictions in permissions and terms

Written permission can make an otherwise restricted image usable, but only if the permission is broad enough. A note that says "you may use this image in your article" might not cover readers who later reuse the article. That is the part many authors miss.

Ask for permission that names the article license. A better permission statement says the image may be included in a CC BY licensed publication and may be redistributed and adapted under that license. If the rights holder refuses that language, the image probably does not belong in a CC BY article.

Watch for restrictions that sound harmless. "For academic use only" conflicts with commercial reuse. "No modifications" conflicts with adaptation. "One-time use" conflicts with redistribution. "Use in this journal only" conflicts with repository deposits, preprints, and later reuse by readers.

Also separate copyright from privacy and ethics. A CC BY compatible image license does not override patient consent, confidentiality, trademark concerns, cultural permissions, or research ethics rules. Human subjects, clinical photographs, Indigenous cultural materials, and sensitive locations may need extra review even when the copyright license looks open.

How to handle adapted figures

Adapted figures need more attention than unmodified images. If you redraw a diagram, crop a photo, translate labels, recolor microscopy panels, or combine panels from several sources, you are creating a derivative or adapted work. CC BY allows adaptation, but the source license must allow it too.

CC BY and CC0 sources are usually straightforward for adaptation. You still need attribution, and you should state that the image was adapted. A simple credit might say, "Adapted from Author Name, Title, Year, CC BY 4.0." Add a license link if the publisher's style permits it.

CC BY-ND sources are usually not suitable for adapted figures. The NoDerivatives condition blocks sharing modified versions. Even cropping or adding labels can count as a modification, so do not use ND images as raw material for your scientific figures unless you have separate permission.

Combining multiple sources also creates stacking problems. The final figure is only as reusable as its most restrictive component. If three panels are CC BY and one panel is noncommercial, the combined figure cannot honestly be treated as fully CC BY compatible.

Build your attribution record as you work

Licensing problems often appear late because authors postpone attribution until submission. That is painful. By then, a figure may be polished, coauthors may have approved it, and replacing one component may disturb the whole layout.

Create a small source log while you build figures. Record the creator, title, source URL, license name, license URL, date accessed, and any changes you made. If you received permission by email, save the email as a PDF with the manuscript files. This habit takes little time and prevents frantic searches later.

If you design figures yourself, keep the project file and asset list. For clean, publication-ready visuals, you can create with Graffiy and stay intentional about which icons, diagrams, and visual elements are original or openly licensed. A clear design workflow makes the licensing review much easier.

Your credit line should be specific enough for readers and editors. Avoid vague wording such as "image from Google" or "source: internet." Good attribution tells people who made the image, where it came from, what license applies, and whether you changed it.

What to do when the license is unclear

If you cannot verify the license, treat the image as unavailable for CC BY reuse. That may sound strict, but it is usually faster than arguing with an editor later. Unclear rights are not compatible rights.

You have several options. Replace the image with a CC BY or CC0 alternative. Redraw the concept from scratch using your own expression. Use your own data to create a new visualization. Contact the rights holder and request permission that explicitly covers CC BY publication.

Redrawing is useful, but be careful. Copyright does not protect facts, methods, or ideas, but it can protect the creative expression of a diagram. If your new figure closely copies the layout, colors, labels, and visual choices of the original, it may still be considered an adaptation. Make a genuinely new figure that explains the idea in your own way.

For essential images, involve the journal early. Editorial offices have seen these questions before. Send the source, license, planned credit line, and how you intend to use the image. You may get a quick answer, and you will avoid last-minute surprises.

A 60-second checklist before submission

Before you submit a CC BY paper, run this final scan on every image and figure component. It is simple, but it catches most problems.

• Can you identify the original source and creator?
• Is the exact license visible on the image page or source document?
• Does the license allow commercial reuse?
• Does the license allow adaptation, if you changed the image?
• Are there any extra website terms that restrict redistribution?
• Is third-party material excluded from the article license?
• Do you have a complete attribution line?
• Have you saved permission records, if permission was needed?

If every answer supports broad reuse, you probably have a CC BY compatible image license. If one answer is uncertain, pause and fix it. The best time to replace a risky image is before peer review, not after acceptance.

A useful rule for open access authors: if readers cannot reuse the image under the freedom your article promises, do not hide that image inside a CC BY paper.

Practical examples open access authors see often

Imagine you find a diagram in a CC BY journal article. The article license is CC BY, but the figure caption says the diagram was reproduced from another publisher with permission. That figure is not automatically covered. You need to inspect the original source or get permission.

Now imagine you find a microscopy image in a repository marked CC0. You crop it, adjust brightness consistently, and include it as a representative visual. That is usually compatible, provided the repository is trustworthy and your scientific handling is ethical and transparent.

Consider a beautiful anatomy illustration marked CC BY-NC. It is free for education, but your CC BY article allows commercial reuse. That noncommercial condition makes it incompatible unless the illustrator grants broader permission.

Finally, consider an icon set from a design marketplace. You paid for it and the terms allow use in publications, but they prohibit redistributing source files or using icons in open templates. That language may not fit CC BY. Use open icons, make your own, or ask for specific permission.

Bottom line: choose images that travel with your article

A CC BY paper is designed to travel. Readers may translate it, teach from it, adapt a figure, include it in a review, or reuse it in a commercial database. Your images should travel with the same clarity.

The safest path is simple. Prefer original visuals, CC BY images, CC0 images, and permissions that explicitly allow CC BY publication. Avoid noncommercial, no derivatives, one-time use, editorial only, and unclear licenses. Keep records as you work.

Good licensing is not paperwork for its own sake. It protects your article's openness, respects other creators, and saves you from avoidable delays. When you can quickly spot a CC BY compatible image license, you can focus on the science and publish with fewer surprises.
