Simply point Google Earth (version 4 and above) at the location you want and drop your images onto Geotagger's icon (in the Dock or Finder). It will fetch the location from Google Earth and write it into the Exif data. Geotagger is free and will remain so, but if you like what I've done you're encouraged to make a small PayPal donation so I can buy an iPhone and start coding for that too.
