Funziona in locale ma online NO! come mai?

[Donovant]

Salve, la cosa è proprio strana, vorrei capire cosa mi sfugge, il seguente codice in locale funziona ma online no....:

var imgs = 0;

window.addEvent("domready", function(){
	
	
	var numR = -1;
	var W = screen.width;
	var H = screen.height;
	
	$("content").setStyles({"left": (W - $("content").getStyle("width").toInt() )/2+"px", "top":"0"});

function show(){
	imgs = 1;
	var req = new Request({
		url:"js/imgs.xml",
		update:$("box_show"),
		onRequest:function(){ $("ajax").set("html","WAITING FOR ANSWER..."); 
			
			var loader = new Element("div",{
									 "id":"loader",
									 "styles":{ "width":"31px", "height":"31px", "border":"0px solid red",
									 			"background-image":"url(imgs/ajax-loader.gif)", "position":"absolute",
												"top":"370px", "left":"455px"
									 }
			}).inject($("content"));
			
		},//END onRequest
		onSuccess:function(txt, xml){
			$("loader").destroy();
			var root = xml.documentElement;
			//$("ajax").set("html","OK!"); 
			imgs = root.getElementsByTagName("img");
			num = Math.round( Math.random() * (imgs.length-1) );
			img = (Browser.Engine.trident)? imgs[num].text : imgs[num].textContent;
			$("ajax").set("html", "OK - "+root.getElementsByTagName("img").length+" - "+img+" - "+num);
			$("box_show").setStyle("background-image", "url(imgs/"+img+")");
			
		},//END onSuccess
		onFailure:function(){ /*$("ajax").set("html","ERROR");*/ }
	}).send(null);
	
}//END show()

function show_slide(){
	num = Math.round( Math.random() * (imgs.length-1) );
	while(num==numR){ num = (num+1)%imgs.length; }
	numR = num;
	img = (Browser.Engine.trident)? imgs[num].text : imgs[num].textContent;
	$("box_show").setStyle("background-image", "url(imgs/"+img+")");
	$("ajax").set("html", img);
}

show();
show_slide.periodical(2000);

});//END "domready"

Le immagini sono state caricate, non capisco proprio.

Risolto....alla fine anzichè scrivere " .send(null); " dovevo scrivere " get(null); "
