iTag is a free tool that allows you to easily add title, description and keyword tags to your digital photos. The data you enter is stored into the actual photo file itself - using the open standard of IPTC. Many applications can read/write the IPTC data, but iTag is especially powerful at editing a group of photos all at once. Geocoding your photos is also straight forward by drag and dropping Google Earth placemarks (*.kml, *.kmz). An even faster way is to simply copy a placemark to the clipboard, which iTag can detect. When geocoding, the data can optionally be saved as IPTC tags (FlickrFly style), to the EXIF fields, or both.
