External Load problem

Hello everyone and happy new year :beer:

I have a problem loading external swf(s) in my file.
So here it goes:
I have created a mini-gallery or whatever , that has a navigation.When you click on the buttons of the navigation I want it to load some other swfs and place them where I want.
How can I do that? Is it possible to be done with both AS2 and AS3?
I would be greatful if someone could help me out with this although it may have been answered before and I am sorry if this is a re-post.
