I want a image to follow the mouse, and I use Image class of Slick 2D:

    public void init(GameContainer gameContainer, StateBasedGame stateBasedGame) throws SlickException {
        mouseImage = new Image("res/mouse.png");
    }
    public void render(GameContainer gameContainer, StateBasedGame stateBasedGame, Graphics  graphics) throws SlickException {
        mouseImage.draw(0,0,0.1f);
    }

But it seems that it does not have method for re-positioning a Image object. So how can I implement it (in `update` method)? Thanks.
