It’s dishonest to call this software free when the license states that Google has a right to use anything you create, forever, in whatever way they want and whoever they want to give it to.
If you take an amazing photo and save it with Picasa, Google can do whatever they want with it. So it’s free to download, and then you give them the right to exploit you. Maybe that would be a fair trade…except for the fact that you cannot take back that right, even long after the software/service is obsolete and gone. Any semi-serious photographer should be wary about using Picasa!
From the license, read starting the 2nd sentence:
11.1 You retain copyright and any other rights you already hold in Content which you submit, post or display on or through, the Services. By submitting, posting or displaying the content you give Google a perpetual, irrevocable, worldwide, royalty-free, and non-exclusive licence to reproduce, adapt, modify, translate, publish, publicly perform, publicly display and distribute any Content which you submit, post or display on or through, the Services. This licence is for the sole purpose of enabling Google to display, distribute and promote the Services and may be revoked for certain Services as defined in the Additional Terms of those Services.
11.2 You agree that this licence includes a right for Google to make such Content available to other companies, organizations or individuals with whom Google has relationships for the provision of syndicated services, and to use such Content in connection with the provision of those services.
Strengths:
Good software.
Weaknesses:
You retain copyright but give Google permission to use your content to make more money. Forever.
