QueryLoader v2 is a better version of the old script posted in 2009. It serves the main purpose of preloading the images on your website by showing an overlay and a loading bar. It automatically fetches all your images and background images and preloads them before showing the webpage. QueryLoader currently works with jQuery v1.9 and in IE version > 7, Chrome, Safari and Firefox.

Include the script in the head section of your webpage.
<script src="path/to/file/jquery.queryloader2.js" type="text/javascript"></script>
Be sure to add it after you include jQuery.
Now call QueryLoader in a $(document).ready() like this:
$(document).ready(function () {
$("body").queryLoader2();
});
For support on iOS devices use the following code:
window.addEventListener('DOMContentLoaded', function() {
$("body").queryLoader2();
});
$(selector).queryLoader2(options);
backgroundColor
(string) background color of the loader (in hex). Default: "#000"

completeAnimation

minimumTime
(int) time in miliseconds which the loading has to run. If time has not passed the animation will still show. Default: 500
