Search the Free-Stock-Photo-sphere
or just Launch PicFindr
PicFindr searches the web for stock photos that are completely free to use commercially. It is a web app that helps you search several stock image, public domain and photo community sites simultaneously.
Several licensing arrangements have recently emerged as alternatives to copyright (sometimes called "copyleft") and PicFindr makes sense of them all by helping you find images based on what you have to do to use them, whether licensed under Creative Commons, GNU, a site-specific agreement, or something else. PicFindr can even find free images you can use commercially without requiring permission or credit of any kind!
PicFindr is still under development, so expect some odd behaviour and inaccurate searches. You can always re-load the page (F5). PicFindr requires the Flash 9 or later browser plug-in.
Do you know of a great stock-photo site that should be included in PicFindr? Tell us
