iStockPhoto has some nice graphics & photos
I use iStockPhoto dot Com. They have all sorts of graphics, images and photos. They are royalty free and usually come in both jpg and eps. The prices vary depending on the art and usually for a little extra money you may reproduce the art and sell retail. There system works by becoming a member which is free, then you buy credits. Each art work is x amount of credits. After paying you download the art and use it. You can browse around there site and see if there is any art that interest you.
