PICASA

Picasa is an image organizer and image viewer for organizing and editing digital photos, plus an integrated photo-sharing website, originally created by a company named Lifescape (which at that time may have resided at Idealab) in 2002 and owned by Google since 2004. "Picasa" is a blend of the name of Spanish painter Pablo Picasso, the phrase mi casa for "my house", and "pic" for pictures (personalized art). In July 2004, Google acquired Picasa and began offering it as a free dounload. Is a very useful program. If you have a Google account, you must have a Picasa account because they use the same mail adress
