Enables the use of lightbox2 which places images above your current page, not within. This frees you from the constraints of the layout, particularly column widths.

  if ($a == $b) {
    return 0;
  }
  return \Drupal\Component\Utility\Unicode::strlen($a) > \Drupal\Component\Utility\Unicode::strlen($b) ? -1 : 1;
}
