I'm trying to design a Flash module for a website and I'm trying to design it in such a way that the original size of the module is about 150px high, but when a button is clicked on this original image, a popout image appears that is much larger in height, about 600px in order to display more information. Is something like this possible?
Unfortunately, no. You have design the the Flash Catalyst file to the maximum size of your element. This might be best solved with some jQuery within the page to display the popout image instead.
