Code

function theme_slick_thumbnail(array $variables) {
  _slick_preprocess_item($variables);
  extract($variables);
  $build = '';

  // Cannot use FIGURE, as both slide and caption are optional. FIGURE makes
  // no sense when only caption is provided for tab navigation, and no image.
  if (!empty($item['slide'])) {
    $build .= '<div class="slide__thumbnail">' . drupal_render($item['slide']) . '</div>';
  }
  if (!empty($item['caption'])) {
    $build .= '<div class="slide__caption">' . drupal_render($item['caption']) . '</div>';
  }
