Lightbox Issue

[labforone/Ben]

Hey guys,

Check out this site.

http://www.stargatefabrication.com - Go to gallery.

So when you click an image, the lightbox works fine. Click one of the options at the top. (Gates, Balconies etc..)
Then try click an image and it simply opens in a new tab.
The 'lightbox_trigger' on the anchor tag is still on the image so I dont understand why it isn't working.

Any help is appreciated.
