'Basically, if you use a smartphone, the picture will have GPS location data embedded, the time you took the photo and the type of smartphone used!!! All a Pikey thief needs to do is open a website .....
Right click the bike's photo, copy the URL onto the webpage and Bish Bash Bosh - he has the Lat/Long GPS data for your house. It even loads a google satellite image.'
So uploading smartphone pics of your bike/garage can give away vital information.
With iPhones you can turn the GPS tagging off. Not sure about other phones. Best idea is to screenshot the photo on a pc, copy into paint and save in there.
