Okay so I think I know WHAT needs to be changed.. I just need to know HOW to modify it so that it displays the thumbnail of the product images on the packing list:

In the admin/super_packingslip.php file, on or around line 201 in the I found:
Code:
          echo '        <td class="dataTableContent" align="left">' . zen_image(DIR_WS_CATALOG . DIR_WS_IMAGES . $products->fields['products_image'] , $order->products[$i]['name'], SMALL_IMAGE_HEIGHT, SMALL_IMAGE_WIDTH) . '</a>&nbsp;</td>';
I am hoping that someone ran into this same issue and knows the answer.. If not, I guess I'll start experimenting with how to remove the product image from the packing list altogether..
