    $image['width'] = $item['width'];
    $image['height'] = $item['height'];

  // processed, the link path must at least be an empty string.
  if (isset($variables['path']['path'])) {
    $path = $variables['path']['path'];
    $options = isset($variables['path']['options']) ? $variables['path']['options'] : array();
    // When displaying an image inside a link, the html option must be TRUE.
    $options['html'] = TRUE;
    $output = l($output, $path, $options);
  }
