Hi, Many image formats' specifications allow for data areas, where information about the subject, the camera, the location and the date and time can be stored, and, where possible, Shotwell reads this information when importing a new image. Most likely, the photos that have tags already had them stored in either their EXIF or XMP data areas by other software, and Shotwell was able to read them. We don't do any image recognition at the moment, although there has been talk of adding face recognition in the future (please see http://trac.yorba.org/ticket/1702).
