Right now there is no solution for this. The slide show automatically expands all images to fill the entire space. The next version (under development right now) will have the possibility to choose between auto-resizing the images, or displaying them in their original format.
So I’m afraid you’ll have to wait for the release of the next version. No release date has been planned yet.

By the way, please ask support questions in the support forum.

I have a litte problem that I hope you can help me with…
The pictures show horizontal images perfectly, but when I add pictures that are taken vertically -they are much to wide. They get dragged out of porporsion if you know what I mean… I assume there is a (probably easy) way to set it so all images is getting showed correctly? I cannot find out how to do that, so if you could help me out here please, I’d appreciate it!?
