Picasa 3.5 available with face recognition / easy geotagging
Picasa is starting to be really the best free picture viewer (beside XnView for converting pictures)
This version bring 2 new highly desirable features
Add name tags – Picasa 3.5 scans all the photos in your collection, identifies the ones with faces, and groups photos with similar faces together. It’s easy to add name tags to dozens of photos at once by clicking “Add a name” below a photo and typing the person’s name. Once you’ve tagged some pictures, you can make a face collage with one click, easily find all your pictures with the same two people in them, or upload your name tags to Picasa Web Albums
See below with an old picture, on the right side, the software detect all faces in pictures an propose you to tag them! (yes this was me when I was 4 years old)
Now, not finding people in your huge library of pictures is a thing of the past.
Geotag your photos with Google Maps – Quickly add geotags using new integrated Google Maps by clicking the Places button in Picasa 3.5, and dragging your photos to the location where you took them. Of course you can stil use Google Earth to tag or view photos if you prefer.
