Custom Forum Icons ~ A Unique icon for Each Forum

[znightmare]

Hi, I would really like some help with my code because I have a custom template, I would be very grateful if someone could tell me which codes I need to enter to make the custom forum icons.

This code below is my entire forumbit_depth1_cat template

Thanks

<div class="forum_wrap">
<div class="thead_main"><div class="thead_left"><div class="thead_right"><div class="thead_wrap">
<div class="expcolimage"><img src="{$theme['imgdir']}/{$expcolimage}" id="cat_{$forum['fid']}_img" class="expander" alt="{$expaltext}" title="{$expaltext}" /></div>
<div class="float_left"><strong><a href="{$forum_url}" title="{$forum['description']}" class="tip">{$forum['name']}</a></strong></div>
<div class="clear"></div>
</div></div></div></div>
<table border="0" cellspacing="0" cellpadding="8" class="tborder">
<tbody class="forums" style="{$expdisplay}" id="cat_{$forum['fid']}_e">
<tr>
<td class="tcat_main" colspan="3"><div class="float_right" style="margin-right: 208px"><span class="smalltext"><strong>{$lang->forumbit_lastpost}</strong></span></div><span class="smalltext"><strong>{$lang->forumbit_forum}</strong></span></td>
</tr>
{$sub_forums}
</tbody>
</table>
</div>
