模板标签里面

在index.html里面如何同时调用一级和二级的自定义标签图片，调用有C1和C2,后台的标签调用工具指引代码，我每个代码都测试了，就是自定义的图片调用不出来，其他的都调用出来了，

 {category module=meiti pid=0 return=c1}
            <div class="col-xs-6 col-sm-4 col-md-3 colpad">
              <div class="itemss inner_item"> 
     
     <img class="angle_fix" src="{HOME_THEME_PATH}zrc/image/angle.png">
     <div class="tubiaoico">
     <a class="a" href="{$c1.url}" title="{$c1.name}" target="_blank"> <img src="{dr_thumb($t.lanmutubiao)}" alt="{$c1.name}" title="{$c1.name}">
                <h3>{$c1.name}</h3>
                <p>{$c1.fubiaoti}...</p>
                </a></div>
                <div class="article_btm clearfix">
    {category module=meiti pid=$c1.id return=c2}
    <span class="fl view"><a class="a" href="{$c2.url}" title="{$c2.name}" target="_blank"><i class="iconfont {$c2.zititubiao}"></i>{$c2.name}</a></span>{/category}
    
    <a class="link fr" target="_blank" href="{$c1.gwlj}" rel="nofollow"><i class="autoleft fa fa-share" title="www.xunruicms.com链接"></i> www.xunruicms.com</a>
    
    </div>
              </div>
