Google Picasa earns enthusiastic reviews from critics who are most impressed with its photo-organizing features, which make it easy to find and catalog large photo libraries. Its image-editing tools are well-liked, though the software doesn't offer the advanced features found on GIMP and in Adobe Photoshop products. But that means it doesn't have a steep learning curve either.
Simple interface. Like many Google tools, Picasa is easy to use and uncluttered. Installation is a breeze. Reviewers love its photo-management features, which make it simple to upload and organize your images. Features include facial recognition, for scanning photos and automatically organizing them by who is in the shot, and geotagging, which lets you add geographic data that can be used for sorting or by other programs (displaying images on a map in Google Earth, for example).ProsGood photo-editing tools, Excellent photo organizer, Supports facial recognition and geotaggingConsNo Facebook or Flickr integration, Editing tools OK for amateurs, not pros
