Comment (by GregLone):

 Erf, I was about to post almost the same thing -_-'

 The difference is I used a filter before the thumbnail creation, so
 plugins can add a title to the attachment if they want (track title? album
 title?).

 {{{
 /**
  * Filter the parameters for the attachment thumbnail creation.
  *
  * @since 3.9.0
  *
  * @param array $attachment An array of parameters to create the
 thumbnail.
  * @param array $metadata   Current attachment metadata.
  * @param array $uploaded   An array containing the thumbnail path and
 url.
  */
 $attachment = apply_filters( 'attachment_thumbnail_args', $attachment,
 $metadata, $uploaded );

 $sub_attachment_id = wp_insert_attachment( $sub_attachment,
 $uploaded['file'] );
 }}}
 Also, I used a post meta to store the hash, but ''post_content_filtered''
 seems to be better. Less easy to get but we won't use it every day.
