在 Internet Explorer 6 及更低版本中,透明 png 无法正确显示。 png的透明部分不是透明的而是纯色的。无论如何,要解决该问题,请将此代码添加到您的 head 标签中。

<script language="JavaScript">
function correctPNG() // correctly handle PNG transparency in Win IE 5.5 & 6.
{
   var arVersion = navigator.appVersion.split("MSIE")
   var version = parseFloat(arVersion[1])
   if ((version >= 5.5) && (document.body.filters)) 
   {
      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
         }
      }
   }    
}
window.attachEvent("onload", correctPNG);
</script>

In Internet Explorer 6 and below, transparetn pngs do not show correctly. The transparent part of the png is not transparent but a solid color. Anyways to fix that problem add this code to your head tag.

<script language="JavaScript">
function correctPNG() // correctly handle PNG transparency in Win IE 5.5 & 6.
{
   var arVersion = navigator.appVersion.split("MSIE")
   var version = parseFloat(arVersion[1])
   if ((version >= 5.5) && (document.body.filters)) 
   {
      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
         }
      }
   }    
}
window.attachEvent("onload", correctPNG);
</script>

显然,我们不知道到底是什么没有正确显示,因为您没有提供任何信息。如果您想在 IE6 中使用透明 PNG 文件,请查看此链接 http: //24ways.org/2007/supersleight-transparent-png-in-ie6

Clearly, we have no idea what exactly is not displaying correctly since you've given no information. If you're looking to use Transparent PNG files in IE6, check out this link http://24ways.org/2007/supersleight-transparent-png-in-ie6

你应该尝试这个

<div style="position:relative; height: 188px; width: 188px;
filter:progid:DXImageTransform.Microsoft.AlphaImageLoader 
(src='images/image.png',sizingMethod='scale');"></div>

或使用从这里下载的JS http://labs.unitinteractive.com/downloads/单位提示.zip
http://www.twinhelix.com/css/iepngfix/

You should try this

<div style="position:relative; height: 188px; width: 188px;
filter:progid:DXImageTransform.Microsoft.AlphaImageLoader 
(src='images/image.png',sizingMethod='scale');"></div>

or use a JS downloaded from here http://labs.unitinteractive.com/downloads/unitip.zip
or http://www.twinhelix.com/css/iepngfix/
