MyBB Community Forums

I want to have a custom image next to each forum icon

Example movies and tv and then a picture of a movie reel next to it

How do I go about doing this for 1.8

This is my forumbit_depth2_forum code what would I change in here to have a custom image for each thingy

<tr>
<td class="{$bgcolor}" align="center" valign="top" width="1"><img src="{$theme['imgdir']}/{$lightbulb['folder']}.gif" alt="{$lightbulb['altonoff']}" title="{$lightbulb['altonoff']}" class="ajax_mark_read" id="mark_read_{$forum['fid']}" /></td>
<td class="{$bgcolor}" valign="top">
<strong><a href="{$forum_url}">{$forum['name']}</a></strong>{$forum_viewers_text}<div class="smalltext">{$forum['description']}{$modlist}{$subforums}</div>
</td>
<td class="{$bgcolor}" valign="top" align="center" style="white-space: nowrap">{$threads}{$unapproved['unapproved_threads']}</td>
<td class="{$bgcolor}" valign="top" align="center" style="white-space: nowrap">{$posts}{$unapproved['unapproved_posts']}</td>
<td class="{$bgcolor}" valign="top" align="right" style="white-space: nowrap">{$lastpost}</td>
</tr>

this guidance should help (though it is for earlier version of MyBB) => custom forum icons
