Hi, I've been trying to figure out why Firebug is giving me the following error on this page. I'm using JQuery 1.2.6 (the gallery script i'm using on the website isn't compatible with 1.3.x) - the error is as follows:

Code:
this.empty is not a function

Line 12
I've not seen this error on other sites where i'm using 1.2.6 - can anyone see why this might be happening? Thanks in advance!
