Not sure if this is just a test page, but since it isn't fixed yet this is what the code inserted into the head should look like:
<!-- Start VisualLightBox.com HEAD section -->
<link rel="stylesheet" href="engine/css/vlightbox.css" type="text/css">
<style type="text/css">#vlightbox a#vlb{display:none}</style>
<link rel="stylesheet" href="engine/css/visuallightbox.css" type="text/css" media="screen">
<script src="engine/js/jquery.tools.min.js" type="text/javascript"></script>
<script src="engine/js/visuallightbox.js" type="text/javascript"></script>
<!-- End VisualLightBox.com HEAD section -->
<link rel="stylesheet" href="engine/css/vlightbox.css" type="text/css">
<style type="text/css">#vlightbox a#vlb{display:none}</style>
<link rel="stylesheet" href="engine/css/visuallightbox.css" type="text/css" media="screen">
<script src="engine/js/jquery.tools.min.js" type="text/javascript"></script>
<script src="engine/js/visuallightbox.js" type="text/javascript"></script>
<!-- End VisualLightBox.com HEAD section -->
As mentioned, the opening and closing head tags should not be there and neither should the two ellipses. Also, the two link tags were closed in the xhtml manner.
For images, when providing text for alt and title attributes, don't put the text in quotes. VSD adds the necessary quotes for you, so instead of alt="Home", you have alt=""Home"". Same with its title attribute. The double quotes can cause problems.
