Loading images externally and randomly (?)

I’m having some difficulties here. I have two swf’s, one controls the other—not the problem. On the one swf there are buttons and the other are images, you rollover a btn a different image pops up…you get the point. Now, on the swf with the images–I am trying to have the images load exteranlly, but also randomly. Is this possible?

Any suggestions would be greatly appreciated.
thanks,
