How to display different logos on selected forums?

[fabaa]

Thank you I've added those body tags to Forumdisplay and Index templates.

My Header template looks like this:

<div id="container">
		<a name="top" id="top"></a>
		<div id="header">
			<div class="logo" style="margin:0 auto;text-align:center"><a href="{$mybb->settings['bburl']}/index.php"><img src="{$theme['logo']}" alt="{$mybb->settings['bbname']}" title="{$mybb->settings['bbname']}" /></a></div>
			<div class="menu">
				<ul>
					<li><a href="{$mybb->settings['bburl']}/search.php"><img src="{$theme['imgdir']}/toplinks/search.gif" alt="" title="" />{$lang->toplinks_search}</a></li>
					<li><a href="{$mybb->settings['bburl']}/memberlist.php"><img src="{$theme['imgdir']}/toplinks/memberlist.gif" alt="" title="" />{$lang->toplinks_memberlist}</a></li>
					<li><a href="{$mybb->settings['bburl']}/calendar.php"><img src="{$theme['imgdir']}/toplinks/calendar.gif" alt="" title="" />{$lang->toplinks_calendar}</a></li>
					<li><a href="{$mybb->settings['bburl']}/misc.php?action=help"><img src="{$theme['imgdir']}/toplinks/help.gif" alt="" title="" />{$lang->toplinks_help}</a></li>
				</ul>
			</div>
			<hr class="hidden" />
			<div id="panel">
				{$welcomeblock}
			</div>
		</div>
		<hr class="hidden" />
		<br class="clear" />
		<div id="content">
			{$pm_notice}
			{$bannedwarning}
			{$bbclosedwarning}
			{$unreadreports}
			{$pending_joinrequests}
			<navigation>
			<br />
