Answer 1

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.

I found this, and it WORKS
<?php
if( has_post_thumbnail() )
{
// check if the post has a Post Thumbnail
echo ' <a href="';
the_permalink();
echo '" title="';
the_title_attribute();
echo '">';
the_post_thumbnail( 'medium' );
echo '</a>';
}
else
{
$imgs = get_attached_media( 'image' );
if( count( $imgs ) > 0 )
{
$img = array_shift( $imgs );
echo wp_get_attachment_image( $img->ID, 'thumbnail' );
}
}
?>

You need to use get_attached_media( 'image', $post->ID );
Using
echo get_attached_media( 'image' );
should work.
