The draw method for this class is slightly different in that the data drawn is dependant upon several things, including the existance of an image shape and its location. When drawing, the instance determines whether a valid source image is available and draws that. If a source image is not available then the instance will draw a red box filling the bounds of the shape instance as well as displaying a cross through that bounding box. Text is also added notifying the user that the image is not available.
