Unfortunately, it's currently not possible to retrieve the author's image using the GraphQL API. You may only retrieve the image associated with the article itself.
Pat Rocchio thanks for the heads up - I couldn't retrieve the image, but that might be because it linked to my gravatar. Not sure now, but after uploading a aseparate image for the user profile, it's fine and working as you say. Great, learned something new again.
