// this variable is used as reference to the image in the end.

// try to access the "content" property of the loader, if it works, there is a crossdomain.xml file.
try{
dO = lInfo.loader.content;
}
// if there wasn't one, we need to put the loader inside another object in order to manipulate it

var sprt:Sprite = new Sprite();
// add the loader to the sprite

}
// from here on you can do anything to the dO variable, rotate it, draw it unto a bitmapData, move it around..
// but first don't forget to add to to some container that is on the stage so you can see it!
