When a skin is adjusted to have less items in the footer, and a particular page has
the remaining ones disabled, the height of the footer shrinks to less than the height
of the contained images.
This is visible (at least in IE7) on one of my history pages:
I have the footer list set to:
$footerlinks = array
('lastmod', 'viewcount', 'numberofwatchingusers', 'credits', 'copyright', 'tagline');
