Hope its a work in progress...

To start, its abundantly clear that there are nowhere near 10,000 pictures. There arent even 1,000. There also also only 4 different random categories that arent much help rather than the 10+ claimed in the description: cars, motorcycles, F1, and close-up. So those could be much better, maybe brands or even just muscle, exotic, tuner, and classics or something.

On the bright side, most of the pictures were somewhat interesting and I havent found any that werent clear and its easy to save them. I also like that all of the pictures are made to fit iPhone/touch backgrounds. Poor organization and only having a fraction of what the title and description claims kills it though. Good thing its free.
