Image move script not working in firefox

[chris1606]

This script floats one image over another (to conterract transparency). It works fine in Opera and Internet Explorer, but the image won't move in firefox. Any ideas how I can get it to work please?

function move() {
	var curleft = curtop = 0;
	var obj = document.getElementById('pic1');
	if (obj.offsetParent) {
		curleft = obj.offsetLeft;
		curtop = obj.offsetTop;
		while (obj = obj.offsetParent) {
			curleft += obj.offsetLeft;
			curtop += obj.offsetTop;
		}
	}
	
	document.getElementById('pic2').style.pixelTop = curtop;
	document.getElementById('pic2').style.pixelLeft = curleft;
}

pixelTop/Left are not supported in Firefox. Use top/left instead.
