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>";

IE6 여부 판단
 
var reIE = new RegExp("MSIE (\\d+\\.\\d+);");
 reIE.test(navigator.userAgent);
var fIEVersion = parseFloat(RegExp["$1"]);
