RISOLTO!

codice:
var interceptMovieClip:Function = function (target_mc:MovieClip):MovieClip {
	var temp:MovieClip = (target_mc._name == "firstMC") ? secondMC : firstMC;
	return temp;
};
var slideShow:Function = function (target:MovieClip, index:Number, shifting:Number) {
	var other = interceptMovieClip(target);
	var int_index = index;
	var mclo:MovieClipLoader = new MovieClipLoader();
	var mcli:Object = new Object();
	mcli.onLoadError = function(target:MovieClip, errorCode:String) {
		if (errorCode == "URLNotFound") {
			slideShow(target, index, shifting);
		}
	};
	mcli.onLoadInit = function(target:MovieClip):Void  {
		trace("img/"+int_index+".jpg");
		int_index += 2;
		var t = new PhotoMatrixMotion(target, "luminance", "normal", None.easeNone, 30, false);
		t.onMotionFinished = function() {
			var a = setInterval(function () {
				clearInterval(a);
				var t = new PhotoMatrixMotion(target, "luminance", "normal", None.easeNone, 30, false);
				t.onMotionFinished = function() {
					mclo.loadClip("img/"+int_index+".jpg", target);
					target.swapDepths(other);
				};
			}, shifting*1000);
		};
	};
	mclo.addListener(mcli);
	mclo.loadClip("img/"+int_index+".jpg", target);
};
//
var time_to_slide:Number = 5;
var firstMC:MovieClip = this.createEmptyMovieClip("firstMC", 1);
var index1:Number = 1;
var secondMC:MovieClip = this.createEmptyMovieClip("secondMC", 2);
var index2:Number = 2;
slideShow(firstMC, index1, time_to_slide*2);
setTimeout(slideShow, 5000, secondMC, index2, time_to_slide*2);
più facile di così... non si può...
scusate... il problema.. che apro il flash... 1 / 2 volte l'anno..




mi terrò più aggiornato!
