I think this is main reason why it won't work on products.tpl vs product.tpl

{if $active_modules.Detailed_Product_Images ne "" && $images}

When you remove the $images from the if statement on both the products.tpl and the javascript file it will work, however the check for detailed images wont work obviously.

Why would this work on the product.tpl page tho? There must be some code somewhere it is parsing the productid fromthe http header when going to the product.tpl page
