Picasa is a great photo editing software application from the good people at that little company known as Google. Google Plus, to be exacting. Picasa, as if you didn't already know by now, is a play on the name "Picaso". Pablo Picasso that is. Perhaps because you can do some things to your photos that fall within the realm of the surreal. With Picasa you can edit and share your photos throughout this wide world of ours with Google plus. Be patient with it and it will serve you well.
