General Support: k2 theme and plogger

I have tried integrating plogger here:
http://www.trondsen.org/gallery/
It looks a bit strange doesn't it.
Here's the code for index.php for Plogger:
<?php require('../wp-blog-header.php');
require('gallery.php'); ?>
<?php get_header(); ?>

<div id="content" class="narrowcolumn">

<?php the_gallery_head(); ?>
<?php the_gallery(); ?>

</div>
<?php get_sidebar(); ?>
<?php get_footer(); ?>


Am I missing something? I followed the instructions here:
