          * set for the post. If it's private, the photo permissions should be set
          * appropriately. But we didn't know the final permissions on the post until

          * post and set them to the same permissions as the post itself.
          *
          * If the post was end-to-end encrypted we can't find images and attachments in the body,
          * use our media_str input instead which only contains these elements - but only do this
          * when encrypted content exists because the photo/attachment may have been removed from 
          * the post and we should keep it private. If it's encrypted we have no way of knowing
          * so we'll set the permissions regardless and realise that the media may not be 
          * referenced in the post.
