Well, I have a problem like these and I've read those answers... let me explain you my problem:
The idea is to mix both images, the background and the foreground. In fact, if I add many 'foreground images', each of them must be 'targets'.
Only imagine a bulls eye and some bullets on them... well, I'd like to show those 'impacts' and any of them can take you to a different page...
Is that clear?
I don't know if I have to use GD or SWF to reach it.
Can anybody help me?
(sorry about my bad english)
