Looking at the pages, I see two problems:
1. I get the error
Uncaught exception: TypeError: Cannot convert 'a.attributes' to object which seems caused by a conflict between two theme js files that are loaded together:
No idea what theme option is responsible but if you can make the theme load just ONE of them instead of both, the error is gone...
2. There is a problem with my plugins way of processing the FancyBox CSS and the fact that your WP site is installed in a subdir. I'll look in to that and get back to you on it ASAP. Meanwhile, switching off the auto-trigger option for images should make the script work (but without automaticaly opening the first image of course)...
