I looked at the demo at
http://www.7dana.com/106.84.0.0.1.0.phtml and noticed the difference in demo that the url linked to the thumbs calls an phtml page istead of the detailed image file directly. There is also a test in the .js looking for an "imagegroup" argument (presumably in the url) to be passed to the script. Im not sure how thats possible if the url is nothing but a hard link to the detailed image file and the stylesheet is handling the rendering of the box to the browser. This is obviously a different implementation than the sourcecode provided. Hrm...stupified atm as to how to resolve this.
