This addon was based on "photo display product customer history" which can be found at http://addons.oscommerce.com/info/6495. All credit goes to the original authors reflex-ocasion and Chadduck. Thank you!
The above mentioned addon was modified to work with the "fancybox", which is integrated in osCommerce 2.3, to display product images in the customer account history (shop side). I also added code to display the product images on the Invoice and Packing Slip on the admin side of the shop. These images can be used as a visual check while building/shipping/receiving an order.
This addon has been tested on a 2.3.1 shop and seems to work perfectly. However, please note that I am not a professional programmer... If you find a mistake please feel free to update this addon. Thank you in advance!
