This addon allows you to add an unlimited number of additional images from your admin. The images are displayed as small icons under the main image for the product page although the layout can be changed via settings in admin. The popup's are controlled with the popular Fancybox code and are impressive. This addon was written for pre-2.3 oscommerce shops but can be converted to work with them. In most cases, no additional cost is involved but it varies with the shop so please contact us if there is any concern about this.
