Preloading Images with jQuery and JavaScript Creating effects on websites using jQuery and other JavaScript has really grown from flashy extras to full on applications in the browser. Part of slick applications is images. They might be part of the content being loaded or something like an icon in an application. A jQuery Script Here is a simple jQuery script to preload the images. (function($) { var cache = []; // Arguments are image paths relative to the current page. $.preLoadImages = function() { var args_len = arguments.length; for (var i = args_len; i--;) { var cacheImage = document.createElement('img'); cacheImage.src = arguments[i]; cache.push(cacheImage); } }})(jQuery) You'll notice that this isn't anything special to jQuery.
