I've found several mods that do all sort of nifty things when you hover over an image in the product information page but what I'm looking for is a way to display the larger image of a thumbnail when hovering over it in the Product Listing Page. You know, the page you go to when you click on a category.

Here is what I have and what I want to do;

When I click on a category it displays product thumbnails 3 columns wide on the right side of the page and on the left side of the page it shows the category image.

Something like this:

x x x --------------------
x x x | category image |
x x x --------------------

(sorry for the rudimentary example).

What I want is when I hover over one of the thumbnails on the left it will swap the image on the right with the large version of the thumbnail.

Hope this makes sense. Is there anyway to do this?
