A-10 are mostly white. So you don't even need a (complete) image for them at all. All you need are 4 small images for each suit (hearts, clubs, diamonds, spades) and 11 images for A,1,2, ... ,8,9,10. Then just write a small routine that 'builds' each card every time a card needs to be drawn.
J, Q, and K might as well be full images.
