what other add ons do you have installed?

I ask cause I have IH2 and lightbox installed and the store works perfectly BUT

I just tried installing the addon to show --on the product info page--when the date of the sale is to end and it works but all my additional images from IH2 disappeared...more on that will be in the proper forum...lol

sometimes they do not play nice together

anyway try reuploading the tpl_modules_main_product_image.php

which goes to includes/templates/your template folder/tpl_modules_main_product_image.php

see if that helps
