Тады так:

<script type="text/javascript">
  var images = new Array("0.jpg", "1.jpg", "2.jpg");

  var loadedImgsCount=0;
				function CntLoad() {
					loadedImgsCount++;
				}

				loadedImgsCount
				for (var i = 0; i < images.length; i = i + 1) {
					$("#img_place").append('<img src="' + images[i] + '" onload="CntLoad()">');
				}
				
	
  var imgTotalWidth = 0;
				interv = setInterval(function() {
					if (images.length === loadedImgsCount) {

						$("#img_place > img").each(function() {
							imgTotalWidth+=$(this).width();
						});

						alert(imgTotalWidth );
						clearInterval(interv);
					}
				}, 120);
</script>
