I would like to be able to show a slide on part of the screen, then add a second photo on another part of the screen, and maybe a third on still another part of the screen. Ultimately, pop up to eight photos on one screen to show a montage of pictures at the same time. Possible with PhotoStory?
I do not think with PhotoStory you can do all that, unless there is a template for the Picture-in-Picture effect. With that said, I use the Movie Edit Pro by Magix now for my photo shows, it has multiple visual tracks so I could have 8, 16, 25 pictures viewed at once... though, I wouldn't suggest it.
