gallery plugin without scripts

Hello,
I have a problem creating galleries on this site:
http://www.impressionistarttattoo.it/?page_id=724

as you can see the lightbox effect don’t work correctly. I tried with other two plugins but I had the same result. the pop up window does not appear. in the plugin forum they told me that happens because is a script inside a template that is based on a script itself…
so I want to ask you if there is any chance of fixin that problem or if anyone knows another gallery-plugin that don’t need scripts.

thanks in advance
