help with PHP (getting thumbnail into related posts widget)

Hi all,

my theme uses the custom field “Thumbnail”, which contains the url of a little thumbnail image for each post. Now I am trying to style the YARPP Related Posts Widget Template to display those thumbnails as well. I actually think it should be easy if I just know some PHP. (unfortunately I don’t).

The theme code that creates the thumbnail looks like this:

<img src="<?php $nothumb = get_bloginfo('template_directory'); $thumb = get_post_meta($post->ID, "Thumbnail", true); if ($thumb == NULL) { echo ''.$nothumb.'/images/defaultthumb.jpg'; } else { echo $thumb; } ?>" height="85" width="65" class="a-left-img" /></div>

Now the YARPP Template: It works fine except for the image, because I can’t get the thumbnail url in there. I get errors whenever I try to add something (or nothing happens at all). I have a URL for every post, so I don’t really need the “nothumb” stuff from above.

The code looks like this:

<?php
if (have_posts()) {
	$output .= '<div class="singlesidebar">';
	while (have_posts()) {
		the_post();
		$output .= '<div class="related"><img src="" height="85" width="65" /><h2"><a href="'.get_permalink().'">'.get_the_title().'</a></h2><p>'.get_the_time('d.m.Y').'</p></div>';
	}
	$output .= '</div>';
}

Now dear PHP-buffs, what should I add to get the image url?
