Hi I have been lurking for a while but finally decided to register and post because I am in need of a photo or picture manager that * Does NOT require import of files (so cannot iphoto) * Supports thumbnail views for browsing * The ability to batch rename * Crop and resize would be nice but not essential - if they are missing there needs to be a 'send to external editor' feature iPhoto, Aperture both require i import. An older version of photoshop elements also did (is that still the case?). Picasa also does. Acdsee for Mac doesn't, but it slow, terrible interface, buggy and expensive. I would prefer not to have to use it.
