Free Backgrounds, Clipart and Animated GIFs
(To the best of my knowledge, these sites allow you to take their backgrounds and graphics free for personal homepage use.  However, I suggest you double check for yourself, especially if yours is a commercial web site.  It's always considerate to have credit links back to your resource sites anyway.)
