actually this code inside the else statement looks well, if there is showing even an image it’s good.
It should show the first image of the post you just display, to debug I sometimes just echo the values I set to see if they match. Sometimes it might be just the styling moving text and images to wrong places.
You could try this:

….
else {
$id =$post->ID;
echo $id;
$the_content = $wpdb->get_var("SELECT post_content FROM $wpdb->posts WHERE ID = $id");
$home = get_option(‚home‘);
$pattern = ‚!<img.*?src="‘.$home.'(.*?)"!‘;
$image_src = $matches[‚1‘][0];
echo $image_src;
preg_match_all …
a reset of the query with wp_reset_query() could help too, try it here:

<?php endforeach; wp_reset_query(); // end of post ?>
<?php } ?>
or here:

<?php endforeach; // end of post ?>
<?php } wp_reset_query(); ?>
(I would have to try too..)

looking at the code again I think you get the matches after preg_match so you could try this by putting "$image_src = ..." below preg_match_allThe line with the comment ($image_src = '';) might help, try without this line first....$the_content =…
