lightbox feature not working in store

[cepsi]

Hi, Ive just recently noticed that the lightbox feature in the store is not working,instead when an image is clicked it just goes to a new page with teh image full sized. I had a search here but the one fix i found (gallery path) didnt seem to work.  Its not majorily important, but does give a more professional feeling to the store. I have enabled the Lightbox feature in store admin.

Im using SMF 1.1.11
Your Version: 1.3.6a Latest Version: 1.3.6a  (store)
TinyPortal v1.0 beta 4 © Bloc

Thx any help appreciated
