Replace photo of Maria Ozawa with painting of Maria Amalia

This image is superior to the existing image for the following reasons:

1. With all due respect to Ms. Ozawa and her photographer, this
Enlightenment era portrait of Maria Amalia of Saxony as Queen of Naples
overlooking the Neapolitan crown by Giuseppe Bonito has greater
historical significance.
2. It is in the public domain, so it does not violate copyright law.
3. It does not portray women as sex objects.
