其實标簽手冊裡(lǐ)有，主要是用到了 str2arr 标簽  代碼如下

<div class="zoombox">
  <div class="zoompic"><a class="example-image-link" href="{$content.pic}" data-lightbox="example-set" 
  data-title="{$content.title}" ><img class="example-image" src="{$content.pic}" width="860" height="580" 
  alt="{$content.title}" /></a></div>
  <div class="sliderbox">
    <div id="btn-left" class="arrow-btn dasabled"></div>
    <div class="slider" id="thumbnail">
      <ul>
      <volist name="$content.piclist|str2arr='***'" id="v" key='k'>
        <li <if condition = "$k eq 1">class="current"</if>><a href="javascript:;" >
        <img src="{$v}" alt="{$title}" /></a></li>
      </volist>
      </ul>
    </div>
    <div id="btn-right" class="arrow-btn"></div>
  </div>
</div>

效果如下：
