This page provides links to search engines that include images--ranging from clip art to photos to sophisticated digital artwork-- that can be REUSED, REVISED, REMIXED, or REDISTRIBUTED more freely than can materials limited by default copyright protection.
Images found in these resources may be in the public domain because they don't qualify for copyright protection (eg. U.S. government documents) or because the copyright protections have expired. Alternatively, they may be explicitly licensed by their copyright owners (through Creative Commons, GNU, or other formulations) for free use and distribution.
Not all images in these resources will be available for REUSE, REVISION, REMIXING, and REDISTRIBUTION.
