I am attempting to preload images using JavaScript. I have declared an array as follows with image links from different places:

var imageArray = new Array();
imageArray[0] = new Image();
imageArray[1] = new Image();
imageArray[2] = new Image();
imageArray[3] = new Image();
imageArray[0].src = "http://www.bollywoodhott.com/wp-content/uploads/2008/12/arjun-rampal.jpg";
imageArray[1].src = "http://labelleetleblog.files.wordpress.com/2009/06/josie-maran.jpg";
imageArray[2].src = "http://1.bp.blogspot.com/_22EXDJCJp3s/SxbIcZHTHTI/AAAAAAAAIXc/fkaDiOKjd-I/s400/black-male-model.jpg";
imageArray[3].src = "http://www.iill.net/wp-content/uploads/images/hot-chick.jpg";

The image fade and transformation effects that I am doing using this array work properly for the first 3 images, but for the last one, imageArray[3], the actual image data of the image does not get preloaded and it completely ruins the effect, since the actual image data loads AFTERWARDS, only at the time it needs to be displayed, it seems.

This happens because the last link http://www.iill.net/wp-content/uploads/images/hot-chick.jpg is not a direct link to the image. If you go to that link, your browser will redirect you to the ACTUAL location. Now, my image preloading code in Chrome works perfectly well, and the effects look great. Because it seems that Chrome preloads the actual data - the EVENTUAL image that is to be shown. This means that in Chrome if I preloaded an image that will redirect to 'stop stealing my bandwidth', then the image that gets preloaded is 'stop stealing my bandwidth'.

How can I modify my code to get Firefox to behave the same way?
