 It's been helpful to add additional HTML to the post thumbnail meta box,
 but without any hooks in [source:/trunk/wp-admin/includes/meta-
 boxes.php at 22924#L1003 post_thumbnail_meta_box] the process is very
 fragile, and and requires the use of Javascript, or removing the
 postimagediv meta box and adding your own meta box.

 [source:/trunk/wp-admin/includes/post.php at 22924#L1115
 _wp_post_thumbnail_html] provides a way to filter the HTML, but function
 is only used for ajax requests.

 The attached patch adds a filter to $thumbnail_html in
 post_thumbnail_meta_box, allowing for some parity.
