Can u check if background image has loaded?

[kostyanet]

To show "wait" indicator I'm using that function:

// divID - ID of some div
// divBackground - url of the loading image
function picBack(divID, divBackground) { 
	var d=document.getElementById(divID);
	if(divBackground=="" || d==null) {noBG(divID); return;}
	var img = new Image();
	d.style.backgroundImage = 'url(img/wait.gif)';
	img.onload = function() {  d.style.backgroundImage = 'url(' + img.src + ')'; };
	img.src = divBackground;

Until divBackground is loaded - script showing animated wait.gif.

There is a key: img.onload= must be before img.src=

I dont sure could this help, but it seems alike.
