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.

 YouTube has expanded the width of the page to 960 pixels to better reflect the quality of the videos being created and the screens that  are being used to watch them. The new, wider player is in a widescreen aspect ratio which will provide with a cleaner, more powerful viewing experience.

All 4:3 aspect ratio videos will play fine in the new player. Want to give feedback to YouTube? Click here.
