Problem with slideshow gallery

[maxpower78]

Hi, I'm trying to create a slideshow in a gallery. I managed to make it work but only if you first click on the slideshow button and then you click on one of the thumbnails. I haven't been able to do just by clicking on the slideshow button. This is the code I used in summary:

package galery {
	public class GaleriaFotos{
		
		public function GaleriaFotos() {
			this.thumbList = new Array();
			this._timer = new Timer(1500);
			this._timer.addEventListener(TimerEvent.TIMER, onTimerEvent, false, 0, true);
		}
		private function init():void
		{
			if (_imageCount == 0)
			{
				for each(var b:BitmapAsset in AssetFilter.getImage(this.assets))
				{
					if (b.id.indexOf(Datos.SUFIJO_SMALL) != -1)
					{
						var name:String = b.id.replace(Datos.PREFIJO_FOTO, "").replace(Datos.SUFIJO_SMALL);
						var index:int = parseInt(name);
						thumbList[index] = b;
					}
					_imageCount++;
				}
			}
			Tweener.addTween(this, { alpha:1, time:1.5, transition:"easeOutQuad" } );		
			
			//slideshow button
			thumbs.slide_mc.buttonMode = true;
			thumbs.slide_mc.addEventListener(MouseEvent.CLICK, doSlideShow);//función en la linea 465
			
			//thumbs click 
			for (var i:int = 1; i < 8; i++)
			{
				var thumb:ThumbHolder = thumbs.getChildByName("t" + i) as ThumbHolder;
				thumb.buttonMode = true;
				thumb.addEventListener(MouseEvent.CLICK, onThumbClick, false, 0, true);
			}
		}

		private function onThumbClick(e:MouseEvent):void
		{			
			var tHolder:ThumbHolder = e.currentTarget as ThumbHolder;			
			cargarFoto(tHolder.fotoId);			
			cualFoto = tHolder.fotoId;
		}
		
		private function cargarFoto(i:int):void
		{
			var foto:BitmapAsset = BitmapAsset(assets[Datos.PREFIJO_FOTO + i.toString()]);
			_currentImage = i;
			if (foto.content == null)
			{
				foto.addEventListener(AssetEvent.ASSET_COMPLETE, resizePhoto, false, 0, true);
				foto.load();		
			}
			else
			{
				mostrarFoto(foto.content);
			}
		}
		
		private function doSlideShow(e:Event):void
		{
		    this._timer = new Timer(1000);
		    this._timer.addEventListener(TimerEvent.TIMER, onSlide, false, 0, true);
			cualFoto ++;
		}
		
		private function onSlide(e:Event):void
		{
			cargarFoto(cualFoto);
			cualFoto ++;
		}
		
		private function onTimerEvent(e:TimerEvent):void
		{
			ocultarControles();
		}
		
		private function hideControls()
		{
			Tweener.addTween(thumbs, { alpha: 0, time: 1, transition: "easeOutQuad", onComplete:function() { _timer.stop(); } } );			
		}
		
		private function showControls(event:MouseEvent)
		{
			if (barra.alpha < 1)
			{
				Tweener.addTween(thumbs, { alpha: 1, time: 1, onComplete:function() { _timer.reset(); _timer.start(); } } );
				
			}
		}
	}
}

What have I do to make it work correctly?

Thank you.

Can you give a more detailed description of how this is supposed to work? A slideshow is supposed to happen when? How does this relate visually to the gallery? ETC ETC.
