Adding keyword tags in Windows Photo GalleryIf you read reviews of Windows Vista in the mainstream media, the criticism you'll find most often is that there's no killer feature. Oh really? These three features - XMP-based photo tagging, integrated search, and speech recognition - certainly qualify. Read Ed Bott's original blog post, Windows Vista's Three Killer Features.
You can add keywords, captions, and ratings to any JPEG or TIFF photo using the Info pane in Windows Vista's Photo Gallery program. Tags are stored as metadata within the file itself using the industry-standard XMP format. As a result, you can copy or move photos without having to export your metadata.
