CollideImage Function?

BlitzMax Forums/BlitzMax Beginners Area/CollideImage Function?

Could someone perhaps provide an example, or a modification of Marks example above which illustrates a more real-world case?

i.e.
Lets say I have a one list of player bullets which I need to test against another list of enemy sprites, resulting the identity of the specific bullet/alien which collided.

Sorry if I'm being thick here but compared to the old Blitz collisions this is making no sense to me at all.
