  </script>
<?php end_slot() ?> 

<div id="gallery">

  <div class="flexslider">
    <ul class="slides">
    <?php $images = ullWidgetGalleryWrite::getImagesAsArray($doc['gallery']) ?>
    <?php foreach ($images as $image): ?>
      <li>
        <div class="slide_container" <?php echo ull_rimg_bg_attributes($image) ?>>
        </div>
      </li>
    <?php endforeach ?>
    </ul>
  </div>
