jQuery Uncaught TypeError: Object # has no method 'on'
on() was only added in jQuery v1.7; Drupal 7 ships with jQuery v1.4, and can be updated to 1.5 using the jQuery Update module. The reason you're getting the error is simply that the lightbox library you're using is written for jQuery v1.7 and above.

See How do I update jQuery to the latest version I can download? for some ideas on how to get round this.
