为什么在list。html无法显示图片了 tag页面就可以

{list action=module catid=$catid field=title,url,updatetime,description,keywords,hits order=updatetime page=1}

      <li class="am-g am-list-item-desced am-list-item-thumbed am-list-item-thumb-left">

        <div class="am-u-sm-4 am-list-thumb">

          <a > <img class="am-thumbnail" src="{dr_thumb($t.thumb, 100, 100)}"> </a>

        </div>

        <div class=" am-u-sm-8 am-list-main">

            <h3 class="am-list-item-hd"><a title="{$t.title}" target="_blank" href="{$t.url}">{$t.title}</a></h3>

            <div class="am-list-item-text">{$t.description}</div>

             <div class="am-list-item-text">{$t.description}</div>

            <span class="am-list-date am-fl" style="margin-top: 6%">浏览：{$t.hits}次</span>

            <span class="am-list-date am-fr" style="margin-top: 6%">时间：{$t.updatetime}</span>

        </div>

      </li>

       {/list}
