 Ok I was researching a little bit and I found this very helpfully:
Code:
 
/*

Correctly handle PNG transparency in Win IE 5.5 & 6.
http://homepage.ntlworld.com/bobosola. Updated 18-Jan-2006.

Use in <HEAD> with DEFER keyword wrapped in conditional comments:
<script defer type="text/javascript" src="pngfix.js"></script>

*/

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
     }
  }
}

 This is what I think it does. You know how on Mozilla Firefox PNG's are transparent if they are suppose to be but not on IE. This codes lets you have PNG's be transparent in IE. Thats what I think.

 Yeah, it basically takes out the blue part of the PNGs in IE.

No, don't put it in the CSS. Put it in your header tags.

Example:
<HTML>
<HEAD>
put code here.
</HEAD>
<BODY>
</BODY>
</HTML>
