Well this is what I came up with. I had to chage the axis because many of my images are tall.
Code:
{* $Id: menu_bestsellers.tpl,v 1.10.2.1 2004/11/16 11:15:01 max Exp $ *}
{if $bestsellers}
{capture name=menu}
{section name=num loop=$bestsellers}
<FONT class="VertMenuItems">
{math equation="value+1" value=$smarty.section.num.index}.</FONT>
<A href="product.php?productid={$bestsellers[num].productid}&cat={$cat}&bestseller" class=VertMenuItems>{$bestsellers[num].product}
<div align="center">{include file="product_thumbnail.tpl" productid=$bestsellers[num].productid image image_y=50 product=$bestsellers[num].product}</div>
</a>
{/section}
{/capture}
{ include file="menu.tpl" dingbats="dingbats_categorie.gif" menu_title=$lng.lbl_bestsellers menu_content=$smarty.capture.menu }
{/if}
