Understanding Image Licenses Without the Headache

"Free" is not one thing. A free image can still come with conditions, and ignoring them is the most common way creators get into trouble — a takedown notice, a bill, or worse if it's for a client. Here's what actually matters, in plain language.

The licenses you'll meet most

• Public Domain / CC0 — no rights reserved. Use freely, for anything, no credit needed. The safest option there is.
• CC BY — free to use, including commercially, as long as you credit the creator.
• CC BY-SA — same as CC BY, but any derivative you make must be shared under the same license. Fine for a blog post, awkward for a closed commercial product.
• CC BY-NC — the "NC" means non-commercial only. Great for a school project, off-limits for anything that makes money.
• Provider licenses (Unsplash, Pexels, Pixabay) — permissive and commercial-friendly, each with their own small print (usually: don't resell the photo as-is, and don't imply the person in it endorses you).

When do you have to give credit?

Whenever the license says "BY". If attribution is required, include three things: the creator's name, the source, and the license — ideally as links. A clean format looks like:

> Photo by *Creator Name* on *Source*, licensed under *CC BY 4.0*.

When credit isn't required, adding it anyway is still a kind gesture that supports the people making this work freely available.

The traps that catch people out

• "Non-commercial" is stricter than it sounds. A monetised blog, a client project, or an ad all count as commercial.
• Editorial-only images can show logos, landmarks or recognisable faces that you *can't* use to sell a product, even if the photo is free.
• People and property need releases for commercial use. A free license covers the photo, not necessarily the right to use someone's face in an advert.
• Licenses can change, but the version you downloaded under still applies — which is why keeping a record matters.

Staying safe in commercial work

• Read the license before you download, not after.
• Keep a simple record of where each asset came from and under what license.
• When in doubt, prefer CC0 or a provider license for commercial projects.
• For anything high-stakes (a paid ad, a product package), lean toward images cleared for commercial use with no attribution requirement.

FAQ

Does "free to use" mean I can do anything with it? No. It means free of cost, but the license still sets the rules — especially around credit and commercial use.

Do I need a lawyer to use free images? For everyday content, no — just follow the license. For large campaigns or anything involving recognisable people, a quick legal check is worth it.
