What is "picasa"

Picasa was 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. In July 2004, Google acquired Picasa from Lifescape and began offering it as freeware. "Picasa" is a blend of the name of Spanish painter Pablo Picasso, the phrase mi casa (Spanish for "my house") and "pic" for pictures.

Native applications for Windows XP, Windows Vista, Windows 7, and Mac OS X (Intel only) were available from Google. For Linux, Google bundled Wine with the Windows version to create an installation package. For Mac OS X 10.4 and later, Google also released an iPhoto plugin and a standalone program for uploading photos.

On February 12, 2016, Google announced it was discontinuing support for Picasa Desktop and Web Albums, effective March 15, 2016, and focusing on the cloud-based Google Photos as its successor. Picasa Web Albums, a companion service, was closed on May 1, 2016.
