Alter Actionscript on small 'card stack' type photo gallery

Action script of Flash project currently loads all images in an XML file into memory and allows flipping the top photo to the back of the stack in order to see the next image. Problem: user can have unlimited number of photos and user photos from modern camera's can be 1MB or more. Solution required: load only 5 images? onto the stage at once.? As the top image is flipped to the back, unload it and load the 6th image into that spot.? This process is repeated until the last image referenced in the XML file is load, at which point, it should start at the beginning... making an endless cycle. The code is very short (less than 200 lines) and should be easy to update.? I will need this work done by the end of this week. ## Deliverables Code is attached.
