替换图标的方法：

一、隐藏本身图标

<style type=”text/css”>#wzlogo{display:none;}#news-header .news-menu a.news-logo { width: 160px; background: url(wz_inc/images/index/logo.gif) no-repeat center center; }</style>

二、替换自己的图标
<img alt=中华中医网 src=upload/?/Templets/image/logo.gif />’ => ‘<img alt=中华中医网 src=wz_inc/images/index/logo.gif />
