aggiungi queste 3 variabili
(comunque lo script non e' fatto bene: non si espone tutto cosi' a livello di window, jquery ha un sistema per estendersi via plugin decisamente evoluto)
$autoplay=true;
$autoplayTimer = 5000;
$autoplayTimeout=false;
e le parti in rosso
codice:
function BackgroundLoad($this,imageWidth,imageHeight,imgSrc){
$this.fadeOut("fast",function(){
$this.attr("src", "").attr("src", imgSrc); //change image source
FullScreenBackground($this,imageWidth,imageHeight); //scale background image
$preloader.fadeOut("fast",function(){$this.fadeIn("slow");});
var imageTitle=$img_title.data("imageTitle");
if(imageTitle){
$this.attr("alt", imageTitle).attr("title", imageTitle);
$img_title.fadeOut("fast",function(){
$img_title.html(imageTitle).fadeIn();
});
} else {
$img_title.fadeOut("fast",function(){
$img_title.html($this.attr("title")).fadeIn();
});
}
if($autoplay) autoplayStart()
});
}
function autoplayStart(){
if($autoplayTimeout) clearTimeout($autoplayTimeout)
if($autoplay) $autoplayTimeout=setTimeout(function(){$nextImageBtn.trigger('click')},$autoplayTimer)
}
chiaramente $autoplay e' un booleano che puoi usare qualora volessi aggiungere all' interfaccia un play/pause
ciao
