I am trying to get Slimbox to work with a modified default theme. This is the page I'm working on; it's the default theme with my existing design inserted into it:

http://www.woodenhorsearts.com/galleries/Camilla-Mead/

I have set everything up following the Slimbox instructions as well as information I have found in these forums; as far as I can tell I've done it right.

However, when I click on the image thumbnails on the page, my browser just goes to the URL of the image; the slimbox pop-up animation function does not happen.

Can anyone please help me figure out what I'm doing wrong?

Zenphoto uses Colorbox, not Slimbox.

Anyway, I visited your site and it works fine with FF8 and IE9.
