If you have a digital camera, Picasa is worth a try. I used the software before Google bought the company and fell in love with its slick, simple interface. My favorite feature is the timeline view, which lets you scroll through your photo collection by the date the pictures were taken, ignoring folders and cryptic file names.
Recently, Google released a new version:
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.
Picasa also makes advanced editing simple by putting one-click fixes and powerful effects at your fingertips. And Picasa makes it a snap to share your pictures – you can email, print at home, make gift CDs, instantly share via Hello™, and even put pictures on your own blog.
Danny Sullivan has an excellent review that compares Google Picasa 2 and Adobe Photoshop Album 2 at Search Engine Watch. I’ve got several thousand digital photos here. I really should get them organized one of these days!
