Link Gravatar to Commentor's Website

Hey 🙂

I’m trying to figure out how to link a commenter’s gravatar to their website if they entered a url (and do nothing if they didn’t) and i would like it to open in a new window (target=”_blank”).

Currently, my comments.php template in the home directory is being driven by a comments.php function in my functions folder.

The part that calls the gravatar, as far as i can tell, is

<div class="avatar">
		<?php echo get_avatar($comment,$size='64'); ?>
		<span class="overlay"></span>
	</div>

…but when i wrap that in a href link it doesn’t work 😐

would REALLY appreciate the help as it’s driving me bonkers!
