html question!

i’m trying to make my kubrickheader.jpg clickable as i removed the blog description and now i can’t click on it to return to main page.

i’ve tried inserting some codes but to no avail. can someone point me at the right direction?

this is the code i’ve tried but fail!

<div class="header" onclick="location.href='http://www.alexlab.com';"></div>

<div id="header">
	<div id="headerimg">

		<h1><a href="<?php echo get_option('home'); ?>/"><?php bloginfo('name'); ?></a></h1>
		<div class="description"><?php bloginfo('description'); ?></div>
</div>
</div>
