This is
untested but...
replace
Code:
<script type="text/javascript">
prodImage='<img src="{$product.tmbn_url}"/>';
prodName='<{$product.product}>';
var p0=('<br/><a href="'+document.URL+'">'+prodImage+'<br/>{$product.product}</a><br/>${$product.taxed_price}<br/>');
</script>
with
Code:
<script type="text/javascript">
prodImage='<img src="{$product.tmbn_url}"/>';
prodName='<{thumb file=$product.tmbn_url width=80 linkonly=Y}>';
var p0=('<br/><a href="'+document.URL+'">'+prodImage+'<br/>{$product.product}</a><br/>${$product.taxed_price}<br/>');
</script>
Also note that the width was set to the same width that was in the CSS.
