This extension modifies the browse_1.php file in Virtuemart, which is the default PHP file for displaying one product per row. Unfortunately it doesn't add the necessary JavaScript to the browse_2.php to browse_5.php files. This means that if you choose to display more than one product per row with the correct "browse" PHP file, the effect will not work on the browse products pages, only the product details pages.

I don't have the necessary skills to modify them myself, but if anybody could create modified versions of these browse PHP files and supply a link for download (not necessarily free) I would be eternally grateful.

Having said that, I still give the extension top marks because it is free, easy to install, configurable and never fails to impress when I show people the effect. If the "browse" PHP files issue is addressed and "close" text is applied to the large image this would be worth paying good money for (and I would).
