Have you considered adding a "pan & zoom" feature? A coworker was really impressed with some of the presentations I made with PicturesToExe and he started try to create similar presentations with his Apple system. He used imovie make a slideshow with music. Then he played with the pan & zoom feature to start on a picture zoomed in and then pan around and zoom out. It almost makes the still jpegs feel like a movie. Thoughts?
