Re: [RCD] Re: Corrupt mail.gif - using PNG

[Michiel Oosterling]

It is so easy to correct broken png issues in IE 5.5 and up.
If we take for granted that RC will only work in newer browsers anyways (I
haven't even tried RC in IE5 or NS6 for instance), then what's the issue
with including the little javascript function below to fix it once and for
all?

[code]
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
             }
      }
   }
window.attachEvent("onload", correctPNG);
[/code]

This will, as far as I've been able to tell, correct transparency issues in
IE every single time.
