I don't see it as a problem.

If the app developer wants to initialise the object with `null` image and a description, why don't we let them do it?

The image may be auto-generated and while it's generated, the image in `ImageIcon` remains `null`; when the image is read the app calls `ImageIcon.setImage` to the set now available image and *expects the description being preserved*.
