function recent_thumb() {
echo "<ul><?php query_posts('showposts=5'); ?>
<?php while (have_posts()) : the_post(); ?><?php $Image = get_post_meta($post->ID, 'Image', $single = true); ?>
<li class="thumbnails"><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>">
<img class="preview" src="<?php bloginfo('stylesheet_directory'); ?>/timthumb.php?src=<?php echo $Image; ?>&h=80&w=100&zc=1" alt=""/>
<span class="title">
<?php the_title(); ?></span></a>
<?php endwhile; ?></li></ul>"
