Menalto gallery

I began using Gallery 1.5 with Mambo; since moved two sites to Joomla!, and installed Gallery 2 together with the Gallery 2 bridge component. Unknown Object

Also since migrated sites to Drupal, which doesn't work with Gallery just now, though still have separate installs of Gallery (versions 2 and 3), on three sites. Info here is from days when I used Joomla w Gallery.
