Clipart and Pictures...a few good sites.

Graphics Gallery  Cute clipart, but not organized...great for those willing to browse.
 
FreeFoto     Don't miss this site if you're looking for photographs.  The selection is remarkable and the quality excellent.
 

Free Animated Gifs     Look for the subject table half way down the page;  clever and attractive.
 

Discovery School's Clipart     Nice collection.  Somewhat limited, but keyed to education.

#1 Clipart    - Indexed by subject.

Clipart at Webplaces.com   Indexed by subject, easy to use, a top notch resource!
