Uview
Years ago when I first began web development one of the first web sites I worked on was an image archiving system called Uview for a printing company. The business relationship continued from then until the present when recently the system was completely redeveloped, using Drupal.
Unfortunatly you can’t see much without logging in but there is an interesting faceted search tool there, a lot of image resizing, exif data extraction and thousands of pieces of content.
