Also, because I rarely take photographs, I have no idea about EXIF data and whatnot. However, unless the envelope is hidden on a bus like in the 638 example used before, what's stopping me using my car to travel wherever I think the envelope is located?
Cos when you upload the photo (doesn't have to be a funky one taken with a flashy camera and doesn't need to show your face), the bus ticket needs to be in shot too.
