如图，首页的品牌推荐的地方，每个品牌的LOGO都会循环两次，请高手帮忙解决一下，brands.lbi代码如下：
<meta http-equiv="Content-Type" c>
<div id="pbrands" class="plbox plborder">
<h3><span>品牌专区</span></h3>
<ul class="listStyle">
<!-- {foreach from=$brand_list item=brand} -->
<!-- {if $brand.brand_logo} -->
<li><a href="{$brand.url}"><img src="../data/brandlogo/{$brand.brand_logo}" alt="{$brand.brand_name|escape:html} ({$brand.goods_num})" /></a></li>
<!-- {else} -->
<li><a href="{$brand.url}">{$brand.brand_name|escape:html}</a> <!-- {if $brand.goods_num} --><span class="textDesc">({$brand.goods_num})</span><!-- {/if} --></li>
<!-- {/if} -->
<!-- {/foreach} -->
</ul>
</div><!-- /brands -->
