I think things are too bloated, as it is.

I want to use this mainly for burning a sideshow onto DVD, and sending to photo editors, publishers, clients, etc.

Right now, it's at 96 pictures. I'd like it to be closer to 50 – or, at most, around 75. If you figure 5 seconds per picture, then even a 50 picture slideshow is over 4 minutes. I don't want to overly tax their attention.
