49 * This class handles saving, fetching creating representations
50 * for all images. The image content is stored in the DB. The content is
51 * written out to a file at the ProducerImages level.
52 * Remember that Handlers for specific image types, Gif, Jpeg, etc..
54 * It implements the MirMedia interface.
56 * slowly starting to look better, a next step would be to have the
57 * representation stuff (WebdbImage) happen here.
