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.

Code

function lightbox2_preprocess_page(&$variables) {
  if (arg(0) != 'node' || arg(2) != 'lightbox2') {
    return;
  }

  //Overwrite template_preprocess_page() region settings.
  $theme = \Drupal::theme()
    ->getActiveTheme()
    ->getName();

  // Retrieve all block regions.
  $regions = system_region_list($theme);

  // Remove all region content assigned via blocks.
  foreach (array_keys($regions) as $region) {
    if ($region != 'content') {
      $variables[$region] = NULL;
    }
  }

  // Set up layout variable to none.
  $variables['layout'] = 'none';

  //additional template files for e.g. page-node-lightbox.tpl.php are allready implemented through template_preprocess_page()
