// To use the preloading make a call like:
// jQuery.preLoadImages("image1.gif", "/path/to/image2.png");
// or
// jQuery.preLoadImages(imageArray);
(function($) {
	var cache = [];
	// Arguments are image paths relative to the current page.
	$.preLoadImages = function() {
		function isArray(obj) {
			if (obj.constructor.toString().indexOf("Array") == -1) {
				return false;
			} else {
				return true;
			}

		if ( isArray(arguments[0]) ) {
			arguments = arguments[0];
