Are you sure sure you don't want to load the pictures before you hit that button? Or is it more that you don't want to show the pictures before hiting it?
If you do, you can use the loadMovie action.
If you don't, you can use scene 1 to navigate, and create another scene which hold your pictures, and just go to one frame of that scene when you click that button. Or make mcs, which again hold your pictures... Set the visibility of those mcs to false at the beginning, and just set it to true when your button is clicked.
