One thing which is lacking in the admin side of x-cart is a way of being able to see instantly which products in a category doesn't a picture. Currently you have to go into each products page and check. With this mod a small icon sized thumbnail will appear next to your product name in the search page.
PS You only need to edit one file, so is very easy to do ...
Filename: main/products.tpl
replace
with
Code:
<td>ID</td><td></td>
just after
Code:
<td width=1%>#{$products[cat_num].productid}</td>
insert
Code:
<td width=20 align=center>
{include file="product_thumbnail.tpl" productid=$products[cat_num].productid product=$product.product tmbn_url=$products[cat_num].tmbn_url image_x=20}
</td>
If you want the thumbnail icons at a different size, just adjust the image_x setting in the include statement.
