Display post excerpts without images.

At the end of each of my pages I display the two latest posts (with a short excerpt) as part of my page footer.

However the images in my posts are screwing it up. Is there a way to call the excerpt excluding the images of a post? It seems as though this should be a simple command, but I can’t seem to find any documentation.

My code:

<div id="latestBlog">
	<?php $temp_query = $wp_query; ?>

<?php
query_posts("cat=7,10,8&showposts=2");

global $more;
// set $more to 0 in order to only get the first part of the post
$more = 0;
?>

<?php while (have_posts()) : the_post(); ?>
  <div class="post" id="post-<?php the_ID(); ?>">

  <h3><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>

 <div class="entry">
   <?php the_content('<span class="moretext">[continue reading...]</span>'); ?>
 </div>
	</div>
<?php endwhile; ?>

</div>  <!-- end #latestBlog -->

You can see how it is screwing up the bottom of my page here: http://benjamincharity.com/freelance/process/

Thanks in advance!
