How to drop in an image gallery viewer in my fla

I downloaded a simple xml image gallery online and would like to put it in my .fla.

It seems like the best way of doing this would be to load it in as an swf.

It seems like a simple task, but what action script would i put on a button to have the image gallery load up upon clicking that button?

I’m using AS2–any other details I should add here?
