An excerpt from an e-mail I received yesterday.
As you may have heard, Picasa, Inc. was recently acquired by Google. This change means we can now offer Picasa 1.6 (the current version of our software) for free. We're thrilled that millions of people will now be able to try both of our revolutionary products - Picasa and Hello.
Although limited it isn't bad for the price. I have previously posted about the free Hello software. I post most of my photos with Hello now.
