get_post_meta or Galleriffic Messes Up Loop

I have a problem with this loop:

<ul>
 <?php if (have_posts()) : while (have_posts()) : the_post(); ?>
 <li>
  <a  href="<?php bloginfo('url'); ?>/wp-content/uploads/<?php $photo_large = get_post_meta($post->ID, 'photo_large', true); ?>
<?php echo $photo_large; ?>" >
<?php the_content(); ?></a>
 </li>
<?php endwhile; endif; ?>
</ul>

The loop occasionally writes the link first, then writes the content after, like this:

<ul>
 <li>
  <a  href="link" ></a>
<p>Some of the content from post...</p>
 </li>
</ul>

I’m not sure if it’s the loop or the Galeriffic script that’s causing this. Any help is GREATLY appreciated.
