If you are trying to get just one image in the post and use it as a thumbail, you might want to try this one:

Add this to you're functions.php :

// Get URL of first image in a post
function catch_that_image() {
global $post, $posts;
$first_img = '';
ob_start();
ob_end_clean();
$output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches);
$first_img = $matches [1] [0];

// no image found display default image instead
if(empty($first_img)){
$first_img = "/images/default.jpg";
}
return $first_img;
}

To call it just put

<?php echo catch_that_image() ?>

in your template file within the loop.

I found this brilliant code from this forum thread. Saved me a lot of times.
