I'm a big fan of design and messing around with photoshop. I design most of my stuff myself including this blog's banner and Kai's birth announcement:
Fotolia boasts an impressive library of just that including vectors and video!
Fotolia also works on a credit based system (credits start as low as $0.75 per) which means that you can get amazing quality stuff for really cheap. No more photoshopping the watermarks out of photos people - you know who you are.
