Unable to enlarge images on nextcode gallery

I have setup the gallery and it displays the images as thumbnails but I can not click on them to enlarge. The cursor changes to the hand to indicate there is a link there but nothing happens

I have tried both short codes, “[nextcode_gallery id_gallery=”1″]” seems to be hidden on the page as expected, but when I use the PHP short code I get the remnants on the page as can be seen.

I have tried using Internet Explorer, Google Chrome and Firefox, no difference.

Any advise

The page I need help with: [log in to see the link]
