Tired of digging through every file and folder on your computer for that photo of your friend’s new baby? Get Google’s Picasa (PC only; www.picasa.com) and it will magically find and display — all in one place — every photo on your hard drive. Then use the program to effortlessly edit, caption, e-mail (snaps are automatically converted to an easy-to-open size and format), and sort into albums without moving pictures from their original folders. Cost of Picasa: free. Never having to search for photos again? Priceless.
