Untuk menulisakan script anda dapat menggunakan apa saja bebas, contoh : Notepad, Notepad++, Dreamwaver, NetBeans, Eclipse.
CSS
Pertama buatlah sebuah folder dengan nama background_slideshow, kemudian buatlah sebuah folder di dalamnya dengan nama CSS, buat sebuah file CSS dengan nama style.css dengan isi script :@font-face {

Javascript
Buat sebuah folder dengan nama js di dalam folder backgroud_slideshow, Kita membutuhkan jQuery jadi download terlebih dahulu file jQuerynya di sini : DOWNLOADSimpan dalam folder yang sama, kemudian buat file 3 buah file java script baru dengan nama
1. jquery.imagesloaded.min.js
(function(c,q){var m="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///ywAAAAAAQABAAACAUwAOw==";c.fn.imagesLoaded=function(f){function n(){var b=c(j),a=c(h);d&&(h.length?d.reject(e,b,a):d.resolve(e));c.isFunction(f)&&f.call(g,e,b,a)}function p(b){k(b.target,"error"===b.type)}function k(b,a){b.src===m||-1!==c.inArray(b,l)||(l.push(b),a?h.push(b):j.push(b),c.data(b,"imagesLoaded",{isBroken:a,src:b.src}),r&&d.notifyWith(c(b),[a,e,c(j),c(h)]),e.length===l.length&&(setTimeout(n),e.unbind(".imagesLoaded",

var cbpBGSlideshow = (function() {

// it takes 3.5 seconds to change the background image
interval = 3500;
function init( config ) {

}
function stopSlideshow() {
isSlideshowActive = false;
clearTimeout( slideshowtime );
}
return { init : init };
})();Perhatikan baris kode script di atas :
// current item´s index
current = 0,
// timeout
slideshowtime,
// true if the slideshow is active
isSlideshowActive = true,
// it takes 3.5 seconds to change the background image
interval = 3500;
Current adalah index gambar anda yang pertama
isSlideshowActive adalah setinggan apakah anda ingin mengaktifkan slideshow atau tidak dengan kata lain apakah anda ingin background anda berganti-ganti atau tidak
inverval adalah settingan interval atau waktu untuk pergantian setiap gambar slideshow
isSlideshowActive adalah setinggan apakah anda ingin mengaktifkan slideshow atau tidak dengan kata lain apakah anda ingin background anda berganti-ganti atau tidak
inverval adalah settingan interval atau waktu untuk pergantian setiap gambar slideshow
FONT
Buat sebuah folder dengan nama Font dalam folder background_slideshow, Font ini digunakan untuk tombol controlnya anda dapat mendownloadnya di sini : Downloadsimpan dalam folder font.
IMAGES
Sekarang untuk gambarnya buat sebuah folder dengan nama images dalam folder background_slideshow, kemudian letakan gambar anda di dalamnya atau anda dapat menggunakan gambar demonya di sini : DownloadHTML
Terakhir Buatlah sebuah file HTML baru di dalam folder background_slideshow, dengan nama index.html dengan isi script :
