[Plugin: jQuery lightBox] Not showing all images on page

Hello, I’m helping a friend use the jQuery lightBox plugin to display their portfolio, and he’s uploaded 8 images on the page but the lightbox only shows “images 1 of 6” and will just loop the first 6 images. I can’t figure out what’s wrong in any of the settings as I haven’t manually edited any code.

Here is the site I’m working on

Thanks!
