////////////////////////
// var imgComp:ImageComponent = new ImageComponent()
// addChild(imgComp);
// imgComp.image = "http://url.com/image.jpg";
// OR a bitmap that is already loaded in
// ////////////////////
//HOW TO SET MaxHeight / MaxWidth
//////////////////////
// imgComp.maxHeight = 200;
// the width will scale in function of the maxheight set.
///////////////////////
// imgComp.maxWidth = 200;
// the height will scale in function of the maxwidth set.
