If you aren't familiar with Picasa, it is one of those programs you have to see and use to be able to appreciate.
Google, the owner of Picasa, has released version 2 of the program. As before, Picasa is totally free and can revolutionize the way you organize and manipulate photos on your computer.
Picasa is software that helps you instantly find, edit and share all the pictures on your PC. Every time you open Picasa, it automatically locates all your pictures (even ones you forgot you had) and sorts them into visual albums organized by date with folder names you know. You can drag and drop to arrange your albums and make labels to create new groups. Picasa makes sure your pictures are always organized.
Quite a few improvements have been made in the new release:
The new version of Picasa released by Google includes advanced editing tools like 12 photographic filter effects, color and lighting adjustments, red-eye removal, photo cropping and straightening; backup capabilities like archiving photos from a computer to a CD or DVD, saving photos on an external drive, and creating gift CDs with personalized slideshows. The latest version also has improved organization and sorting of images. Users can add captions, search across all photos on a computer and attach labels and stars for better photo organization, reorder pictures and clean up cluttered folders. --Techtree
