Windows Photo Gallery
Windows Photo Gallery (formerly known as Windows Live Photo Gallery) is an image organizer, photo editor and photo sharing app. It is a part of Microsoft's Windows Essentials software suite.
Features
Windows Photo Gallery provides management, tagging, and searching capabilities for digital photos. It provides an image viewer that can replace the default OS image viewer, and a photo import tool that can be used to acquire photos from a camera or other removable media. Windows Photo Gallery also allows sharing of photos by uploading them to SkyDrive, Flickr and Facebook.
Photo management
Windows Photo Gallery provides the ability to organize digital photo collection in its Gallery view, by adding titles, rating, captions, and custom metadata tags to photos. There is also limited support for tagging and managing video files, though not editing them.
Windows Photo Gallery uses the concept of hierarchical tagging (e.g. People/Jim, Places/Paris) to organise photos. Deleting a tag from Windows Photo Gallery will also remove it from all photos in the utility. Adobe Systems's Extensible Metadata Platform (XMP) metadata standard, a descendent of the ubiquitous Exif standard which almost all digital cameras currently support, is also supported. This allows for data such as the tags to be stored and edited much more efficiently than EXIF or IPTC.
