Fixed it!
skin1/customer/main/product
s.tpl and find:
Code:
{* SAFETYNET DSEFU MOD *}
{if $enable_seo_links == "Y"}
<A href="{seo_link prod_name=$products[product].product prod_id=$products[product].productid}" title="{$products[product].product}">{include file="product_thumbnail.tpl" productid=$products[product].productid image_x=$config.Appearance.thumbnail_width product=$products[product].product tmbn_url=$products[product].tmbn_url class="NoBorder" alt=$products[product].product|escape}<BR>{$lng.lbl_see_details}</A>
{else}

{/if}
{* END SAFETYNET DSEFU MOD *}
and change it to:
Code:

{if $enable_seo_links == "Y"}
<A href="{seo_link prod_name=$products[product].product prod_id=$products[product].productid}" title="{$products[product].product}">{include file="product_thumbnail.tpl" productid=$products[product].productid image_x=$config.Appearance.thumbnail_width product=$products[product].product tmbn_url=$products[product].tmbn_url class="NoBorder" alt=$products[product].product|escape}</A><BR>

I'm not really sure if it's the image mod or DSEFU, regardless that should get rid of the line under the thumbnail.
