Huge banner like as on MyBB

[.m.]

can we have your forum url and code from header template of your forum's current theme

basically header template consists of code like below

<div id="container">
	<a name="top" id="top"></a> 
	<div id="header">
        <div class="logo"><a href="{$mybb->settings['bburl']}/index.php"><img src="{$theme['logo']}" alt="{$mybb->settings['bbname']}" title="{$mybb->settings['bbname']}" /></a></div>
	<div class="menu">

logo related code can be moved out of the header div and can be adjusted with the required css style
