Ok, you will want to edit your subcategories.tpl. Look for this line of code:
Code:
{if ($navigation_page eq "")||($navigation_page eq "1")}{$current_category.description|regex_replace:"/[\n]/":"
"}
{/if}
replace it with this:
Code:
{if ($navigation_page eq "")||($navigation_page eq "1")}
<table width="100%"><tr><td>[img]{if $current_category.icon_url}{$current_category.icon_url}{else}{$xcart_web_dir}/icon.php?categoryid={$cat}{/if}[/img]</td>
<td>{$current_category.description|regex_replace:"/[\n]/":"
"}</td></tr>
</table>{/if}
Let me know how it works.
