If you have an image which has transparent IE 6.0 and early users see with the white background color. IF you want to fix it here is the JavaScript code.

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  
    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
  }
