使IE6正常显示png图片

方法一：

请将下面代码，加在</html>之后
<!--[if IE 6]>

<script type="text/javascript">
function correctPNG()

{

for(var i=0; i<document.images.length; i++)

{

var img = document.images[i]

var imgName = img.src.toUpperCase()

if (imgName.substring(imgName.length-3, imgName.length) == "PNG")

{

var imgID = (img.id) ? "id='" + img.id + "' " : ""

var imgClass = (img.className) ? "class='" + img.className + "' " : ""

var imgTitle = (img.title) ? "title='" + img.title + "' " : "title='" + img.alt + "' "

var imgStyle = "display:inline-block;" + img.style.cssText

if (img.align == "left") imgStyle = "float:left;" + imgStyle

if (img.align == "right") imgStyle = "float:right;" + imgStyle

if (img.parentElement.href) imgStyle = "cursor:hand;" + imgStyle

var strNewHTML = "<span "+ imgID + imgClass + imgTitle + " style=\"" + "width:" + img.width + "px; height:" + img.height + "px;" + imgStyle + ";" + "filter:progid:DXImageTransform.Microsoft.AlphaImageLoader" + "(src='" + img.src + "', sizingMethod='scale');\"></span>"

img.outerHTML = strNewHTML

i = i-1

}

}

}

correctPNG();

</script>
