I upgraded today, and I couldn't figure out why my main footer (not the Plogger one but the main site template's footer) was being overridden by the large image on picture.php. I found that there' s a missing div, at least this is what fixed it for me...
At the bottom of picture.php, find this:
} else { print "No such image"; } ; plogger_get_footer(); ?>
And replace with this:
} else { print "No such image"; } print '</div>'; plogger_get_footer(); ?>
