I see what you mean Al,
I tried it with 13 picures labeled 1.jpg thru 13.jpg.
When I onClick_ButtonBackward from pic 13.jpg it goes to pic 11.jpg.
I don't know why but this must be fixed before releasing this version of the
Slide show. Also I would like to point out that the folder has about 20 more
none picture files in it. But I don't believe thay have anything to do with
the problem. 

Thanks for bringing this to my attention.
I'm going to work on a solution right now.
