Hello,
A while back I stumbled across a bit of script that I could add to my preloader that would check and see if the images were actually preloading. It would pop-up an alert box when all of the preloading was finished. Being the clever person I am, I seem to have *cough* 'lost' that bit of script. I have searched high and low, but I have been unsuccessful at locating it on the web again. It went something like this:
function preLoad() { image01 = new Image();
image01.onload = loadCheck;
image01.src = "images/aticob.jpg"; image02 = new Image();
image02.onload = loadCheck;
image02.src = "images/primerb.jpg";
}}
This bit of code is missing something though. Namely what to do with the loadcheck data, and popping up the alert box. I am a JS rookie at best, although like many, I can hack together what I need, but this is evading me. Can anyone help me out with this?

I guess you could make the function loadCheck count until it reaches the number of images you're preloading:
var count = 0;
function loadCheck() {
count++;
if(count == 5) {
alert("I'm ready!");
}
}
function preLoad() {
image01 = new Image();
image01.src = "images/aticob.jpg";
image01.onload = loadCheck();
// et cetera
}
Please note I haven't tested this...

That was it. I'll try it and go from there. Thanks, I just don't trust preloaders on there own when designing!
