Remove strange arrow

Hello people
I’ve installed WP with the White-as-Milk theme and only plugins are the share and follow plugin and the G-Lock Double Opt-in Manager plugin. WhenI added a headerimage to the site using the code below, a small arrow ocurred above the headerimage. How do I get rid of this? I googled and searched and tried, but it won’t go away.
A: Open up header.php and look for these lines:

<div id=”headerimg”>
<h1>/”><?php bloginfo(‘name’); ?></h1>
<div class=”description”><?php bloginfo(‘description’); ?></div>
</div>

and replace it with this:
<div id=”headerimg”>
<p>/”><img src=”MYIMAGEHERE.JPG” alt=”<?php bloginfo(‘name’); ?>” />
</p>
</div>
