Some related posts not showing images

I just updated to the latest yarpp and yarpp-experiments, but no difference. If you go to http://www.whatsthatbug.com/2012/11/06/cat-faced-spider-2/ you can see exactly what I’m talking about. All the posts have Related Posts, but a subset of those Related Posts have text but no image. And I’m at a loss.

Any suggestions on where to look?

Here is my template that I’m using:

<br />
<?php /*<br />
Example template<br />
Author: Archon Digital (Jonathan Cuevas) http://archondigital.com/<br />
*/<br />
?><h3>Related Posts</h3><br />
<?php if ($related_query->have_posts()):?><br />
<ul class="related-posts"><br />
        <?php while ($related_query->have_posts()) : $related_query->the_post(); ?><br />
        <?php $the_title = the_title('','',FALSE); if (strlen($the_title) > 40) { $the_title = substr($the_title, 0, 40) . "..."; } ?></p>
<li>
                <a>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><br />
<img src="<?php echo getPostThumbnail(); ?>" alt="<?php the_title(); ?>" width="75" height="75"/></a></p>
<p>                <div style="text-align:center">(<?php echo get_the_date('m/d/Y'); ?>)</div><a>" rel="bookmark"><?php echo $the_title ?></a></li>
<p>        <?php endwhile; ?></p>
<p><?php else: ?><br />
<p>No related posts.</p><br />
<?php endif; ?><br />
