docs: Sets the image of the given object. The image is loaded from this
  instance's {@link ImageSource} using a key in the format
  
  <pre>
  &lt;objectName&gt;.image

  If the image source cannot find an image under that key, the object's
  image will be set to null.
  
  @param configurable The object to be configured. Must not be null.
  @param objectName The name of the configurable object, unique within the
  application. Must not be null.
  
  @throws IllegalArgumentException if either argument is null.
