Hello Mr. Rawles,
I just got a link to a New York Times article about geotagging through Michael Yon's web site, but with the New York Times date of August 11 2010, you may have seen this already. Regards, Albert U.
I have been using the Exif JPEG header manipulation tool for several years. A batch file can be written to remove EXIF data from all images in a folder. I have my wife do this before she uploads her photos to Facebook. Regards, Lee H.
