I have version 4.0.12 and did the following to get thumbnails for all the email invoices and notifications:
First I made a new product_thumbnail.tpl in the same directory and called it product_thumbnail2.tpl
Code for product_thumbnail2.tpl:
Code:
{* $Id: product_thumbnail2.tpl,v 1.14 2004/06/24 09:53:29 max Exp $ *}
{if $config.Appearance.show_thumbnails eq "Y"}<IMG id="{$id}" src="http://www.systemskins.com/image.php?productid={$productid}{if $file_upload_data.file_path}&tmp=y{/if}"{if $image_x ne 0} width="{$image_x}"{/if}{if $image_y ne 0} height="{$image_y}"{/if} alt="{$product|escape}" border="0">{/if}
After that I changed the order_data.tpl:
Code:
{include file="product_thumbnail2.tpl" productid=$product.productid image_x=60 product=$product.product tmbn_url=$product.tmbn_url id="product_thumbnail"}
I hope this helps. Good luck!
