DESPARATE plea: Photo gallery help!

I’m working with this template: http://www.flashvista.com/flash_templates_photography/ enter keyword search of 9476 to view the template.

I’m working with MM MX PRO 2004 (and I know very very little about this program). I ONLY want to edit text and swap in my own photos. I ran into trouble when it comes to the individual gallery sections and the thumbnails. There are 10 thumbnails in a gallery. When I’ve filled up those 10 thumbnails and linked the correct fuller size photo to go with… how do I get the “next” button at the bottom to call up the next set of photos to fill the thumbnails? Is this “swap image” or “disjointed rollovers”? I haven’t been able to find a tutorial that doesn’t talk over my head (remember I’m not familiar with MX other than placing photos and exchanging text… I know nothing about scripting, yada yada… I’m only a photographer!!!), and I haven’t been able to find a visual tutorial that related to what I’m trying to do. For example, in the “places” gallery… I might have 40 photos to use in the gallery but obviously there are only 10 thumbnails. I need this spelled out in the most easiest terms possible. Yes, I’ve read. and read. and read some more. I don’t get it… HELP!
Thanks to anyone who might take on this challenge, I would sincerely appreciate all your time and efforts to help me understand what to do. I don’t want to become a flash guru, I just want my gallery to work. I’ve been asking at forums all over and no one seems to respond so if anyone could point me in the right direction you have no idea how grateful I would be.
Regards,
