Lightbox script not running on the sidebar images

Hey all,

This should be simple to work out but I have tried everything I can think of to no avail so hopefully someone here can shed a little light on what I am doing wrong.

Here is my site: http://www.neoteros.com/

If you click on any of the sidebar pictures you will see that the lightbox script does not run and the picture is simply opened in the same window.

I have tried using the internal script, not using it, using the lightbox WP plugin, playing around with all of the options in the lightbox and the WPG2 lightbox settings page all to no avail.

Strange thing is it was working yesterday, not sure what I did to screw it up but obviously I did something.

Anyone be able to help?
