product detail in modal window?

I'm putting a site together that has a relatively small number of items per category. The full category listing appears on the home page and includes a "add to cart" button for each item. If the client needs more information they click the image (or link) to go to the product detail page. Is there a way to set the link to load the product detail in a modal window instead of a new page?

Sure. You need to edit the file "listing_img_**" (** depends on the item box layout you're using) of the view "product" via the menu Display->Views and add
class="modal" rel="{handler: 'iframe', size: {x: 450, y: 480}}"

in the a HTML tags there and also add the line below at the top:
<?php JHTML::_('behavior.modal'); ?>

Thanks Nicolas - works fine!
