Blink with dynamic jpg transitions?

Got stuck,

please look at http://www.xmoment.nl/flashTest/home.html

i got the images and text dynamic loaded, but i get a pesky blink between transitions.

Any ideas tips how to prevent this?

Part of my code


function preload () {
	var t = container.getBytesTotal (), l = container.getBytesLoaded ();
	var tt = containerBG.getBytesTotal (), ll = containerBG.getBytesLoaded ();
	if (t && l == t) { //wanna be sure container is loaded
		//container._visible = true;
		if (tt && ll == tt) { //be sure containerBG is loaded
			//containerBG._visible = false;
			clearInterval (myInterval);
			gotoAndPlay (2); //both are loaded so go
		}
		// end if
	}
	//end if
}
//end preload
loadMovie (pathToPixs + "image" + bgPic + ".jpg", "containerBG");
loadMovie (pathToPixs + "image" + whichPic + ".jpg", "container");
myInterval = setInterval (preload, 5);
