[FL5] Error, loading images externally

Hi everybody on Kirupa.

I have been experiencing an odd problem with the programming of my website.

I decided to load externally all the pictures on all my galleries since embedding the images into the .swf will (obviously) increase the size of the file.

Now, I was able to make them to load, but the percentage indicator is not working, the pictures take a while to load but… ahmm… I better suggest to see by yourself the error:

(in case you wan`t to see, open any of the first buttons “diseño grafico” or “ilustracion”).

this is the code I am using:

onEnterFrame = function ()
{
	startLoading("graphics/design/poster_kinta.jpg");
	_root.grupo1.poster_01.infoField.gotoAndStop(1);
	_root.grupo1.poster_01.box1.gotoAndStop(1);
};

function startLoading(whichImage)
{
	loadMovie(whichImage, _root.grupo1.poster_01.imageLoader);
	onEnterFrame = function ()
	{
		infoLoaded = Math.round(imageLoader.getBytesLoaded());
		infoTotal = Math.round(imageLoader.getBytesTotal());
		percentage = infoLoaded / infoTotal;
		_root.grupo1.poster_01.box1.box2.infoField.text = Math.round(percentage * 100) + "%";
		if (infoLoaded == infoTotal)
		{
			delete onEnterFrame;
			this.imageLoader.forceSmoothing = true;
			_root.grupo1.poster_01.box1.gotoAndPlay("fadeout");
			_root.grupo1.poster_01.mypreview._visible = false;
			_root.grupo1.poster_01.box1.box2.infoField.text = "listo";
		}
	};
}

Here is a screenshot of the structure of each button:
