image management

ACDSee, F-spot, Shotwell, DigiKam, and IrfanView all provide some sort of image management from basic to Pro. None of them work on the Web. I looked for an equivalent based on Drupal for flexibility and found nothing. I wrote file/image management applications before Drupal, ported some to D4, D5, D6, and am looking to start again in D7. Is this the right group to discuss image management?
