In order to test the prevalence of these tags and analyze the information leaked via EXIF tags, we collected 15,291 images from popular image hosting site Twitpix.com...

399 images included the location of the camera at the time the image was taken, and 102 images included the name of the photographer....

The lion share of images that included GPS tags came from iPhones... It not only includes the phone's location, but also accelerometer data showing if the phone was moved at the time the picture was taken and the readout from the build in compass showing in which direction the phone was pointed at the time...

The picture at the Afghan - Pakistan border shows a pizza... Osama got away again I guess.

Actually I think its a quiche, and they are bloody lucky Osama hasn't called a bombing into that location.
