1) Script Title:

Image Thumbnail viewer II
plus
Lightbox v2.03.3

2) Script URL (on DD):

http://www.dynamicdrive.com/dynamicindex4/thumbnail2.htm

and

http://www.huddletogether.com/projects/lightbox2/

3) Describe problem:

Thanks before for your cool script Image Thumbnail viewer II that works fine, I love it!

I tried to integrate it with latest version of Lightbox in this way:

http://84.233.163.172/testgallery/

Image Thumbnail viewer II (modified) shows the medium images in "loadarea div"
and then clicking on the loaded image, Lightbox shows its enlargement.

It seems to work with IE6 and IE7 but using FF (PC version), I have a broken css on first enlargement (only) of image 2 or 3 (where Image Thumbnail viewer II initialize Lightbox).

I'm still new to JS so any help would be greatly appreciated!
