Loading external swf

so i want a portfolio viewer. i have a scroll menu to choose image. When you choose an image, an external swf will load in a little image window. with a description of the work… And at thebottom of this external swf i want a “view” option which allows the user to view the image full screen or at least the full size of the movie stage. But since this “view” button is in the external swf, how do load the full image on the main swf?
