  // @TODO: Validate that if we have no $uri that this is a valid file to
  // save. For instance, we may only be interested in images, and it would
  // be helpful to let the user know they passed the HTML page containing
  // the image accidentally. That would also save us from saving the file
  // in the submit step.
  // This is kinda a hack of the same.
  // This should use the file_validate routines that the upload form users.
  // We need to fix the media_parse_to_file routine to allow for a validation.
