Javascript preloader

I currently have this script which shows a loading bar within a layer and when all elements have loaded the layer hides itself. It works fine just to load the visible elements, but I have many rollover images, which it doesnt seem to be preloading? I can see it is still loading the elements in the browser loading bar at the bottom right.

What I want it to do is leave the loading layer visible until it has loaded all images?

<!-- Begin
function loadImages() {
if (document.getElementById) { // DOM3 = IE5, NS6
document.getElementById('hidepage').style.visibility = 'hidden';
else {
if (document.layers) { // Netscape 4
document.hidepage.visibility = 'hidden';
else { // IE 4 = 'hidden';
// End -->

<body OnLoad="loadImages()">

<!-- PRELOADER -->

<div id="hidepage"
style="position: absolute;
background-color: #253E6C;
layer-background-color: #253E6C;
height: 100%;
width: 100%;">

<table height="100%" width="100%" align="center">
<tr><td valign="middle" align="center">
Page loading ... Please wait

all you have here is a fake loader.

It is not preloading anything at all.

To preload images you need to use this

img1 = new Image();
img1.src = "/images/img1.gif";
img2 = new Image();
img2.src = "/images/img2.gif";


And so on.

In order for your fake progress bar to work, you would need to use setTimeout and set it to hide after n of seconds

is there a way so i can have a preloading bar that truly simulates the progress of the loading?

Server Side Yes

Client Side? Not Really,but here is a link to (kellybelly) site she is developing and she has a progress bar on it. I do not think she will mind me posting the link to it. View her source and you will see how she done it
client side, yes, too. you have to put, say, 10 layers like <DIV ID=L0>0%</DIV>, <DIV ID=L1>10%</DIV>, ... in the very beginning of the document; than, after equal portions of html to load, put

... of coz, positioning, initial invisibility, etc, applies, but you got the picture, right ?
