Openverse is a search engine for openly licensed media, including photos, illustrations, audio, and video. It indexes content from Flickr, Wikimedia Commons, museums, and other sources, and every result is either in the public domain or available under a Creative Commons license. You can filter by license type, source, and file format. The site shows attribution requirements clearly, so you know what you need to credit if you use an image.

It was originally called CC Search and was built by Creative Commons before being adopted by WordPress. It's a useful resource for bloggers, designers, and anyone who needs images for a project and wants to avoid copyright issues. The library is large and the search is fast, making it a practical alternative to stock photo sites.
