post).

 Here is my Example I'm using:
 Running a script below (placed in the wordpress docroot) to delete all
 thumbnails from the database:


 {{{
 require_once("wp-load.php");
 echo 'Working... '; ob_flush();
 global $wpdb;
 $attachments = $wpdb->get_results("SELECT * FROM $wpdb->postmeta WHERE
 meta_key = '_thumbnail_id'");
 foreach($attachments as $attachment){
      $wpdb->query("DELETE FROM $wpdb->postmeta WHERE meta_id =
 '$attachment->meta_id' LIMIT 1");
      wp_delete_attachment($attachment->meta_value, true);
 }
 echo 'done!';
 }}}

 Now after running something like above I'm left with (inside my content of
 each post) a stale image class tag that no longer points anywhere.

 I think a simple regex replace of the post_content for wp-image-####
 Inside an Image tag would remove the stale element.

 I haven't checked this with other attachment types to see if it also
 exists, but my guess is it would.
