2. About -Picasa is used for organizing, viewing and editing digital photos. It also has an integrated photo-sharing website. It was originally created by a company named Lifescape in 2002 and owned by Google since 2004. -The name ”Picasa" is a blend of the name of painter Pablo Picasso, the phrase mi casa (Spanish for "my house") and "pic" for pictures.

3. Organization and editing -For organizing photos, Picasa has file importing and tracking features, as well as tags, facial recognition, and collections for further sorting. It also offers several basic photo editing functions. -Other features include slide shows, printing, and image timelines. -Images can also be prepared for external use, such as for e-mailing or printing, by reducing file size and setting up page layouts. There is also integration with online photo printing services. -Other simple editing features include adding text to the image. Picasa supports Google's WebP image format as well as the JPG format and most Raw image format (RAW files). A user can view and edit RAW files and save the finished edit (as JPG, or other forms) without any changes to the original RAW file.

4. Keywords -Picasa uses picasa.ini files to keep track of keywords for each image. In addition to this, Picasa attaches IPTC Information Interchange Model (IPTC) keyword data to JPEG files, but not to any other file format. Keywords attached to JPEG files in Picasa can be read by other image library software like Adobe Photoshop Album, Adobe Bridge, Adobe Photoshop Lightroom, digiKam, Aperture, and iPhoto.

5. Searching and Viewing Picasa has a search bar that is always visible when viewing the library. Searches are live, so that displayed items are filtered as one types. The search bar will search filenames, captions, tags, folder names... Picasa also has an experimental feature that allows searching for images that contain certain colors with the "color:" operator. Picasa has no separate view window. There is only an "edit view" with a viewing area. Fullscreen view is available through the context menu of Windows Explorer, and provides a way to start the Picasa editor as well.

6. Face recognition On August 15, 2006, Google announced it had acquired Neven Vision, whose technology can be used to search for features within photos such as people or buildings. Google applied this technology for face recognition, and this functionality was launched on Picasa Web Albums in 2008. Neven Vision incorporates several patents specifically centered around face recognition from digital photo and video images.

7. Geotagging Since June 2007, Picasa can write geographic coordinates to Exif metadata, thus geotagging an image. Since version 3.5 of Picasa, Geotagging may be done directly inside Picasa. The geotagging functionality is described in the Picasa User's Guide.

8. “Hello” Hello by Google's Picasa was a free computer program that enabled users to send images across the Internet and publish them to their blogs. It was similar to an instant messaging program because it allowed users to send text, but Hello focused on digital photographs. Users can opt to view the same pictures as their friends in real-time. One of the advantages claimed at the website is that photos could be shared through firewalls. Hello's service was canceled at the end of 2006, and users were instructed to try the Picasa 'Blog This' functionality for uploading pictures to their blogs. According to the official website, the Hello project was shut down in 2008.
