That's good. Next step is to eliminate your voodoo code:

and look for the actual problem ("the images never show"). You shouldn't assume
that the problem is with the 2 image 'drawInRect:…' messages. It could well be
that the earlier code in 'drawRect:' has done something wrong.
My guess is that an earlier part of 'drawRect:' failed to save/restore the
graphics context around some drawing that changed then invalidated the current
context.
