Question about blogtitle

Hi

I need some help to remove the blogtitle:
I don’t want to have a title in my header image so I deleted the text but there is still a little black square on the header image. I tried to remove it to delete this (in the header.php):

<div id=’headerLogo’>
<h2>‘><?php bloginfo( ‘name’ ) ?></h2>
</div>

But it didn’t work. Click here to see it

Thank You so much for Your help..
Regards Sario
