Picasa quickly finds and organises all the pictures on your pc including the ones you forgot you had. Picasa organises your entire collection while you watch, scanning the images on your computer and automatically sorting them by date.
Move and re-name pictures from inside Picasa. Want to clean up messy folders and move pictures around on your computer's hard drive? Simply drag and drop pictures from one folder in Picasa to another. Picasa will make the change permanent after double-checking with you. Want to change a picture's filename from 671056398a.jpg to Lisa.jpg? In Picasa, it only takes seconds to re-name one picture or a group of pictures.
Make an album. Use the 'Albums' collection to tag your photos into quick groupings inside Picasa. Viewing and sharing the pictures you grouped under an album is easy – they make great slideshows and movies or you can email them to friends.
Add a star rating. Give a gold star to any photo you love: it turns your favourites into visual standouts at a glance. Picasa even has a star search that reduces your entire photo collection to the best of the best in less than a second.
