Integration of YUI Java (Lightbox) in Lectora

Hi there!

Does anybody know how to integrate a YUI Java code (this one: http://nicora.net/projects/photoViewer/index.cfm/demos) in Lectora? It has to be YUI (Yahoo User Interface) code because I'm working with moodle (it really sucks).

Or is there a possibility to create an effect in Lectora which is similar to the Lightbox pop up?

I'd like to use thumbnails. By clicking on them a pop up window opens which contains a larger picture. The rest of the screen should be greyed out (example: http://lokeshdhakar.com/projects/lightbox2)

Would be great if You could help me.

Thank You so much!

Greets,

Sandra
