CSS "has its moments" in such cases...

To answer your questions, we don't use javascript for the thumbnails, we only use it for the popups.

If the thumbs don't display as they should it's because the installation did not go wellm probably. Please try to reinstall the plugin, you won't need to remake your galleries..  ;)

Report back, a URL would also help...

It's a CSS rendering issue mainly, we can't do much about it.

The only thing we could do is add tables in the structure as an alternative and let people decide which one to use (CSS or tables?)... But that will come in later versions...

Here is one of the pages Im having the prob with...

surely there must be something wrong I did?

OK, in your case the problem is different. The thumbs should cover all available "text" space. Since there is no text in this content item, the available "content" width is null, thus thumbs align to the least possible width (=the width of the thumb). Try adding 2 lines of text and you will see that thumbs will work just fine.

Why this happens? It's due to the way content items are constructed in Joomla! The main text is inside a TD which does not stretch to the available space.

A solution to your problem would be to add this right before your gallery in HTML mode:

This will force the container TD to stretch. It can of course be implemented otherwise by modifying your template, but you should ask your template provider for that.  ;)
