Photo Scroll on Theme

Hello,

I was wondering if someone could help me with a thumbnail photo scroller. As you can see from my site rpedigo.com I am using the same theme as this. Now for some reason I can’t get the photos to show up in the scroller. I did the custom field thing where you need to add the name “thumbnail” and then the location of the image, but for some reason nothing wants to surface. Any ideas on what may be wrong, or if I’m doing something wrong?
