Favorite websites for graphic resources

What are the first websites you always check when looking for a graphic resource (vectors, stock images, brushes, wallpapers, etc.)?

I browse for most things on DeviantArt, there are thousands of artists that have great designs. The other day I spent like 2 hours downloading all kinds of wallpapers for my desktop.

IconFinder.net, on the other hand, is always the website I check first whenever I'm looking not only for icons, but also larger images that go great with headers.
