As I stated before, I also could not get the slideshow thing running properly for several reasons (see above). Sorry, but I was just brainstorming at that point.
You may get it to work, but you need to make sure of a couple of things:
Is your slideshow.txt file actually named slideshow.txt? Mine came out named slideshow.lst.
Did you remove the paths in the slideshow.txt (or .lst) file?
I don't know if you will be able to get it to work or not. In my preliminary tests I could not. I will be happy to keep brainstorming with you, though.
Edit: I just looked at the link JnMHayes posted and it looks like it might be just what you need.
