Easy preload image

Ok, I'm sure this will only take half a second. I remember seeing this somewhere. What I want is to load "pictures/navbarbg2.jpg" in javascript. I have a image swap on a picture, and when I hover over one picture, there is a blink where the image is loading. If I have javascript put the hover image on cache, I think that will remove the blink.

there're about a million scripts for this, but here's mine:

function preLoad(args){
	if (document.images){
		var img = new Image();
		var failed = [];
		img.onerror = function(){
			failed[failed.length] = this.src;
			if(args.length > 0){ this.src = args.shift(); }
		}
		img.onload = function(){
			if(args.length > 0){ this.src = args.shift(); }
		}
		img.src = args.shift();
	}
	else { var failed = args; }
	return failed;
}

use it like this:

preLoad(["pictures/navbarbg2.jpg"]);
preLoad(["preloading.jpg", "multiple.png", "files.gif"]);

Well, it seemed to work (always hard to tell). Thanks a lot.
