I can't find any other post with a similar problem, so I think that maybe is a new bug.
Under IE 6,7,8 if someone wrap the links for an image gallery, and then assign as id to the wrapper the key "images", IE throws and error on line 52, char 296.
I fixed the problem on my local changing the id of the wrapper, but as we all know, IE is a headache, so it take some time to find the problem.
as an example:
That code will not work in IE.
Let me know if it's a real bug or it's just my error :)
On the other hand, great work with the plugin, very nice and handy
