png图片在ie6中灰色背景终极解决方案

 

.reset_pass_con_icon{ 
        width:55px; height:60px;
         background-image:url(../images/icon/reset_pass.png)!important;/* FF IE7 */ 
         background-repeat: no-repeat; 
        _filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='../images/icon/reset_pass.png'); /* IE6 */ 
        _ background-image: none; /* IE6 */ }

 注意：1.!important要加载background-image后面保证火狐浏览器显示
          2._filter中的路径用相对路径
