First.... Its not a free use site unless used only for personal pages. Either way, this site has the most extensive collection of background image tiles I have seen to date. And some are very elegant looking http://www.eosdev.com Too bad that they only issue license for "sets" rather than a certain number of them. But with that many tiles, it would be hard to keep track by licensing permissions for hodge podge collections. Pick the graphics and check out the backgrounds. The number of categories is impressive.
