Two simple questions

[bigleo23]

I have two problems that I know I am over thinking.

First, I want to know how to alternate between two images at random, but I only want one image to show up per movie play. basically like a alternating background.

Second, I have a main swf file, I want to load another swf on top of that in a specific location, because the second movie is smaller than the other I still want to see the first level but no matter what I try I cannot get the second file to load in that specific location.

For the first question in the tutorials section of this website you will find a component and how to use it about "loading dynamic background"
FOr the second question you should send some code and sample
