Picasa for Mac is available for free download in US English at: http://picasa.google.com/mac/.

Picasa for Mac makes it easy to manage large photo collections and helps users make professional-looking edits without any technical knowledge, including:

• A drag-and-drop photo collage tool that gives users control over layout and content
• A retouching brush to wipe out scratches and blemishes - and repair old photos
• A slideshow movie maker that uploads users photo montage videos to YouTube with a click
• Smart auto-cropping that guides users on how to zoom in on their subject
• And, auto red-eye removal.

Many of us take pictures so that we can show them to the people we care about. Picasa for Mac integrates seamlessly with Picasa Web Albums, Google's free photo-sharing site, which offers features like name tags - the ability for users to automatically organize and share their photos based on the faces in each picture.
