Picasa is free software from Google, 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 will recognize. You can drag and drop to arrange your albums and make labels to create new groups. Picasa makes sure your pictures are always organized.
I downloaded it and Love it!!! The software works with online services like Hello, which lets you look at pictures with friends and family. Both are free and well worth a look at.
