Where to find images you can actually use: public domain, Creative Commons, and the traps

Every small business that starts publishing content hits the same wall within a week: you need images, stock photo sites want real money, and grabbing something from a Google image search is how you end up with a copyright demand letter for $800. Meanwhile there are millions of genuinely free, legal, often beautiful images sitting in places most people never look.

Here is the map, from safest to most caveated, plus the checking habit that makes all of it safe.

First choice: federal photo libraries (public domain)

Work created by U.S. federal agencies is generally public domain: free to use, even commercially, no permission needed. The quality is often outstanding, and almost nobody uses these.

• NASA for anything space, science, or technology. Spectacular and free.
• National Park Service, U.S. Forest Service, and the Bureau of Land Management for landscapes, outdoors, nature, and recreation.
• NOAA for weather, ocean, and climate imagery.
• USDA for food, farms, and agriculture.
• The Library of Congress and the National Archives for historical photos.

Search "[agency name] photo library" or add site:.gov to an image search. One honest caveat: being on a .gov site does not automatically make an image public domain. Agencies sometimes host contractor or donated photos with separate rights, so check the credit line on the specific image. If it says the agency took it, you are clear.

Second choice: Wikimedia Commons and Flickr's license search (Creative Commons)

Creative Commons images are free to use if you follow the license terms, which nearly always means crediting the photographer.

• Wikimedia Commons holds over 100 million files. Every file page states its exact license. Look for "Public domain," "CC0," "CC BY," or "CC BY-SA." The number after CC matters: BY means credit the creator; SA means anything you make with it must carry the same license, which is fine for a blog post and worth a thought for a logo.
• Flickr has a license filter in its search (look for "Any license" and change it to "Commercial use allowed"). Some of the best nature and city photography on the internet is here under CC licenses, including entire official accounts from government agencies.

The attribution habit that keeps this painless: put the credit right in your post ("Photo: Jane Smith, CC BY 2.0") or in the image caption. It takes ten seconds and it is the whole license fee.

Third choice: Unsplash, Pexels, and their cousins

These sites offer free photos under their own permissive licenses, no attribution required (though appreciated). Two honest caveats keep this category third instead of first:

1. The look. Everyone uses them, so their most popular images read as generic. Search deeper than page one.
2. The fine print. Their licenses prohibit reselling the photos themselves and have gotten more restrictive over the years (Unsplash added a paid tier; some content on these platforms is now promotional). The license today is fine for blog posts and social; just do not build a product around redistributing the images.

The two traps to know about

Trap one: "royalty-free" does not mean free. It is a pricing model on paid stock sites. If you did not get the image from a source above or pay for it, do not use it. Google Images is a search engine, not a license.

Trap two: the license lives on the image, not the website. A Creative Commons site can host an all-rights-reserved photo; a .gov page can host a contractor's copyrighted image. Always check the individual image's license line. Thirty seconds, every time.

Keep a record (the five-minute insurance policy)

Make a simple spreadsheet or doc: image file name, where you got it, the license, the creator, the date. Paste the URL of the license page. If anyone ever questions an image, you answer in one minute instead of one panicked afternoon. This is also a perfect job for an AI assistant if you have set one up: paste the image page URL and ask it to add the row.

What about AI-generated images?

They solve the license problem (current U.S. guidance treats purely AI-generated images as uncopyrightable, and the tools' terms generally allow commercial use) and create a taste problem: obviously AI-generated art on a small business's page can read as cheap. Useful for abstract backgrounds and illustrations; risky for anything meant to look like your real work, your real team, or your real products. Never use AI images that could be mistaken for photos of your actual business; that is a trust issue, not a legal one.

Start this week

Next time you need an image, spend the first five minutes at a federal photo library or Wikimedia Commons instead of a stock site. Check the license on the actual image, write the credit line, add the row to your record. You will have better-looking content than the businesses paying for page-one stock photos, at exactly zero dollars.
