Hover Image on Product Listings?

Hi,

I was wondering if anyone knows how to do this:

For all of my product listings, I need the thumbnail of the products to turn black & white when the user hovers over it.

I know how to do mouseovers, but I'm not sure how to get around this with the way the images are stored. A preferred solution would be an all-css solution that works on all browsers where I wouldn't have to create extra b&w thumbnails, but if not, what other solutions are there?

I am using Zen Cart v1.3.8.

Any help would be greatly appreciated!!

Thanks!

anyone? please?

I use Cherry Zen, but there is a mod that I will be applying after I get finished with all of the really hard back end stuff for my site.

anyway, in the download section and here is the link:
http://www.zen-cart.com/index.php?main_page=product_contrib_info&cPath=40_47&products_id=117

you will find a mod that is called:
Image Handler 2 for v1.3.x

I would believe this is what you are needing.

Let me know how it goes.
