Fantasy stock photos or cheap art for CCGs

[amnion]

Does anyone know of anywhere I could get artwork that doesn't have to be bespoke for an indie CCG?  Having hundreds of cards would get pretty expensive if you had to pay lots for each and every piece of art.  That's why I'm looking for something like a stock photo scenario so the process doesn't get too unwieldy.  And because the artwork can make or break an otherwise awesome CCG, I'm in need of some good artwork, but I don't really foresee having a lot of options for saving money on that part. Maybe someone knows about something cool that I don't.
