Item viewer work complete to use Superfish Menus correctly, and also migrated the item viewers from images of buttons to CSS buttons.  Also changed the background transparency on some images for zooming and set the background to generally be darker for the default look.  Completed adding a TEST viewer, for use with menu testing initially.
