Well, I'm fired again.

It is finding my template, but I'm getting weird results and some images show up, some do not (though all are in the same directory and show up in the template file when it's viewed directly).

I'm seeing this when I view the source in my browser:

' . $sitetemplate_bottom);

Sigh. So near and yet...
