Unload jpeg movie?

Hi
bit of a noob
I have a two scenes, in the second scene I load an amon.jpg

second frame action script in scene 2:

_root.createEmptyMovieClip(“container”, 2);
container.loadMovie(“amon.jpg”);
set(container._x=15, container._y=120);
_root.onMouseDown = function() {
startDrag(“container”);
};
_root.onMouseUp = function() {
stopDrag();
};
