Add preloader to emptyMovieClip

1

I did a search but couldn’t find exactly what I was looking for. I’m loading an external jpg into an emptyMovieClip (AS1) on the [COLOR=Blue]_root[/COLOR] timeline and I want to implement a preloader so when the jpg loads it fades in, not show up abruptly.

Here’s my code:

// Load an external Image
function loadImage(imageFile) {
	var imageFile;
	_root.createEmptyMovieClip("photoHolder",-16384);
	loadMovie(imageFile,"photoHolder");
	photoHolder._x = 7;
	photoHolder._y = 90;
	photoHolder._alpha = 0;
	photoHolder.alphaTo(100, 2.5, "easeOutCirc");
}

Thanks for any help!!
