Yes, it is the folder that the domain is in. But shouldn't be referenced as a folder in the domain. In other words, the folder irc_site is the folder that is the domain. But this folder is an add-on domain on another domain. It resides within the main domain.
Right now it is calling the images from: a01_62c.jpg as if the irc_site is a folder in the domain, but it is actually the domain folder.
I don't know if that makes sense?
It should be just a01_62c.jpg
It is referencing the js files just fine: "/galleries/galleries/ribbon_fullsize/js/gallery.js
