First, I want to give big thanks to all the help I got on my questions for making a Vegas slideshow. (Especially you MrTexTJ)
As it turns out, I've been having lots of trouble because my computer is old, and has very little memory or hard drive. (Who knew that was important?)
Anyway, I ended up going back to photopeach, and, while I still had lots of issues with the computer stalling and freezing, I managed to get a couple shows put together before Windows told me to knock it off and booted me out altogether.
