IE6下png格式透明图片显示灰色的解决办法.

<!--[if IE 6]>
        <script type="text/javascript" src="/scripts/js/plug/DD_belatedPNG.js"></script>
        <script language="javascript" type="text/javascript">
        $(function(){
            DD_belatedPNG.fix(".ml_fix_png");
        });            
        </script>
        <style type="text/css">
            body{behavior:url(/content/images/csshover.htc);}
        </style>
    <![endif]-->

然后再在图片里加上样式ml_fix_png,即可.
