Lightbox doesn't work

http://destinyimage.com/our-authors/

I am working on a site for my client. I am not the original developer. I am having a difficult time troubleshooting the issue with my gallery. I am unable to get the lightbox working. Whenever I click an image I am just taken to image location.

From what I can tell it is a mootools conflict but I am not sure how to fix it. Could someone please help me?
