Workaround (area rel) for Lightbox using Firefox

Hi folks,

This post is kept in English, because of some users in the Lighbox forum (Thread) having the same problem.

Bug description
Using Lightbox 2.04 with area tags an rel="lightbox" or rel="lightbox[Group]" in Firefox will result in a java-script error.

Reason for the Bug:
rel is not an attribute of area neither in HTML 4 (see nor in XHTML 1.0 Strict/Transitional (see and take a look at the DTS..).
Consequence: imageLink.rel doesn't work with Firefox.

But Prototype is still able to get the attribute :)
So just replace imageLink.rel with Element.readAttribute($(imageLink), "rel") and enjoy Lightbox!
