Hi, I want to integrate lightbox 2.0 into my cart ( http://www.huddletogether.com/projects/lightbox2 )

I want to edit tpl_modules_main_product_image.php so that the image that it links to is just the filename for the large image, with the normal medium image as the thumbnail to click on.

I just dont know how to remove the popup code and have it insert the normal filename for the image like

Any ideas?
