Picasa 3.9 finally has great integration with Google+, allowing you to easily upload and share photos on the service and tag friends. Even if you don’t use Google+, you might want to download the update for new editing features.
Thanks to Google+, Picasa users — whether they’re on Google+ or not — can now upload virtually all photos to their accounts without going over the storage limits; the same holds true for videos 15 minutes or under. A new photo-tagging feature lets your Google+ friends tag your public photos.
Windows/Mac: The most noticeable update to Google’s photo-editing software is “Face Movies”, or videos of particular contacts that keep their face framed in one spot. But there’s also desktop editing through Picnik and far better Picasa Web Albums integration.
