Your Template's editable head regions have been removed. Only you could have done that. When you created the gallery, our system examined your template and, finding no editable head region, placed the links to the IGM script and CSS files in the only place possible -- at the end of your first and only editable region. This places them below the actual gallery markup: a place where the script cannot possibly work.
You can repair your Template by opening the DWT file and fixing the head. In your DWT, locate the closing head tag:
</head>
Make a new line above it and enter this code:
<!-- InstanceBeginEditable name="head" -->
<!-- InstanceEndEditable -->
Save the DWT file.
Now open the page that contains your gallery and locate the following two lines of code, on or near line 80:
<link href="p7igm/p7IGM01.css" rel="stylesheet" type="text/css" media="all">
<script type="text/javascript" src="p7igm/p7IGMscripts.js"></script>
Delete them.
Now select your gallery and open the IGM2 interface, as if you were going to edit it.
Click OK.
The script and CSS links should be placed in the editable head region.
Additionally...
By default, all Dreamweaver Templates get two editable regions in the head. The first surrounds the TITLE, enabling you to set a unique title for every page. The second is the editable HEAD region. So, while we helped you fix your editable head region, you should also recreate an editable region around your title:
<!-- InstanceBeginEditable name="title" -->
<title>CSS Page Builder Magic 2: Layout 2</title>
<!-- InstanceEndEditable -->
Obviously, CSS Page Builder Magic 2: Layout 2 is not a good title for your page and should be made more relevant.
