I am trying to create a movie in which there are bitmap pictures which slide into location from the left. These pictures will be both portrait and landscape. Each picture is made into a movie clip and then all the picture movie clips are then grouped together into another movie clip. As each picture slides into place, a door (like an elevator door) will slide open revealing a picture with masking effect. The door will slide open just enough to display one entire picture (no less and no more) whether it is portrait or landscape. My question is using Flash 5, how to create this sliding door effect to accommodate both portrait and landscape when a button is released and a picture slides into place?
