028 * Serializes {@link BufferedImage} pet photos to {@code image/png}/{@code image/jpeg} byte streams.

030 * <p>
031 * Petstore-local port of the deleted {@code juneau-examples-rest} image demo, relocated here (rather than
032 * {@code juneau-examples-core}) so {@code juneau-petstore-core} stays free of any dependency on the examples
033 * modules.  Wired into {@link org.apache.juneau.petstore.rest.PetStoreResource#getPetPhoto(long)}.
