The fastest way is probably to check for collision on the four "corners" of each
image rectangle.  However, that leaves a lot to be desired as far as accuracy is
concerned.  One method I use is to store the coordinate outline of each image
and check if two images overlap at any point.  It's more time-consuming, but
it's more accurate.
