What you're doing doesn't look sensible! A Bitmap is a subclass of Image, so you can always take a Bitmap object and refer to it as an Image, but you can't guarantee that any particular Image is a Bitmap. If it isn't, you will end up with an exception being thrown.

You can create a new Bitmap from an Image, but you have to do that by creating a new instance, like

Image i = some image...
Bitmap b = new Bitmap(i);

That is not casting, that is creating a new Bitmap object, but is a) legal and b) sensible.
