+/**
+ * This class handles saving, fetching creating representations
+ * for all images. The image content is stored in the DB. The content is
+ * written out to a file at the ProducerImages level.
+ * Remember that Handlers for specific image types, Gif, Jpeg, etc..
+ * should override it.
+ * It implements the MirMedia interface.
+ * <p>
+ * slowly starting to look better, a next step would be to have the
+ * representation stuff (WebdbImage) happen here.
