Gemer Theme not displaying picture just red X

Using 2.8.3 or 2.8.4

The Gemer theme is terrific for me, but the image in the post doesn’t display on the home page in the smaller preview area. The image shows up on the feature area but not the lower area on the home page.

Please take a peek http://www.speedthroughcollege.com and see if you can help me. the index page code is this:

“<?php get_header(); ?>

<!– BEGIN content –>
<div id=”content”>

<!– begin featured news –>
<div class=”featured”>
<h2>Featured News</h2>
<div id=”featured”>
<?php
$tmp_query = $wp_query;
query_posts(‘showposts=3&cat=’ . get_cat_ID(dp_settings(‘featured’)));
if (have_posts()) :
while (have_posts()) : the_post();
?>
<!– begin post –>
<div class=”fpost”>
“><?php dp_attachment_image($post->ID, ‘thumbnail’, ‘alt=”‘ . $post->post_title . ‘”‘); ?>
<h3>“><?php the_title(); ?></h3>
<p class=”details”></p>
<p><?php echo dp_clean($post->post_content, 300); ?></p>
</div>
<!– end post –>
<?php endwhile; endif; ?>
</div>
</div>
<!– end featured news –>

<?php
$wp_query = $tmp_query;
if (have_posts()) :
$odd = false;
while (have_posts()) : the_post();
$odd = !$odd;
?>

<!– begin post –>
<div class=”<?php if ($odd) echo ‘uneven ‘; ?>post”>
<h3>“><?php the_title(); ?></h3>
“>
<?php $screen = get_post_meta($post->ID,’screen’, true); ?>
<img src=”<?php $values=get_post_custom_values(“post-image”);echo$values[0];?>”alt=”post-thumb”class=”post-image”width=”150″/>
<div class=”postmeta”>
<p class=”category”><?php the_category(‘, ‘); ?></p>
<p class=”comments”><?php comments_popup_link(‘No Comments’, ‘1 Comment’, ‘% Comments’); ?></p>
</div>
</div>
<!– end post –>

<?php endwhile; ?>

<div class=”postnav”>
<div class=”navigation”>
<div class=”alignleft”><?php next_posts_link(‘« Older Entries’) ?></div>
<div class=”alignright”><?php previous_posts_link(‘Newer Entries »’) ?></div>
</div>
</div>

<?php else : ?>
<div class=”notfound”>
<h2>Not Found</h2>
<p>Sorry, but you are looking for something that is not here.</p>
</div>
<?php endif; ?>
