What is the best solution for photo organization for Mac OS X, non Intel systems?

Running Os X Tiger on an older G4 machine. Anyone know any solutions for free photo organization? I wanted to use Picasa but that is Intel only. I thought about using Iphoto but honestly I don’t think it’s that good and the photos I need to organize- I want to have a new seperate library for them. I hate how Iphoto needs a copy of the photo in it’s own library. I tried I love photos but didn’t like it’s organizing features. Anyone know of some decent shareshare that won’t move my photos around?
