Enlarge pictures

[LilyS]

I have a problem with my Coppermine gallery (http://fan-sites.org/tarja/gallery/index.php).
When I try to enlarge a pic, the pop-up don't open. I run this gallery since 6 or 7 months, and I had never had this problem.

For example, this picture: http://fan-sites.org/tarja/gallery/displayimage.php?album=101&pos=2
should open in a pop-up for the real size. I don't understand what's wrong, I've changed nothing but it's not working. 

Please, could someone help me?

you have over-modfied your custom theme. Reference to scripts.js should be in it, but it isn't. Moving this thread from "Installation & Setup" to "Themes" sub-board.
