Implement image gallery

Gallery: johnw would like to try setting up a gallery by following the book Using Drupal, chapter 7, which gives a complete walkthru. If that works there's yet other things that can be done to improve it further, e.g. some of the recipes on drupal.org use nice ways of mousing over thumbnails and bringing up larger versions with translucency. But if any of us have already set up a gallery in Drupal then that would be good news!
