If not perhaps consider paying one of the illustrators (Daniel González stuff looks excellent) to make you a set of illustrations which are all in the same style - your pages would look a lot more coherent if they didn't have a grab-bag of styles going on, and also you could have a lot of liability if you don't have permission for every image on your site.
It's not really on to just copy images from the web without attribution or payment - you could be sued for a lot of money for that basecamp image for example which is still up.
Otherwise, it's a nice site and great idea though.
