Сделал так:

package classes
{
	/**
	 * ...
	 * @author Scorpion
	 */
	import flash.events.*;
	import flash.display.*;
 
	[Embed(source = "../../img/background.png")] private const Embed1:Class;
	[Embed(source = "../../img/head.png")] private const Embed2:Class;
	[Embed(source="../../img/menuline.png")] private const Embed3:Class;
 
 
	public class Image extends Sprite 
	{
		public static function addImage(i1: int, i2: int, i3: int): Bitmap
		{
			switch(i3)
			{
				case 1: return new Embed1() as Bitmap;
				case 2: return new Embed2() as Bitmap;
				case 3: return new Embed3() as Bitmap;
			}
 
			var image: Class;
 
			var newImage: Bitmap = new image();
			newImage.x = i1;
			newImage.y = i2;
		}
	}
}

Теперь красным в коде privat'ы подчеркивает в private const Embed1:Class и остальных. Когда менял на паблики - тоже не пашет.
