There's a useful thread over on Trackday Riders on the subject of photographing your bike at home using a smart phone, and then posting the image on-line.
Unless the Location facility on the phone is turned off, it uses GPS data to embed the precise location of the photograph in the file so villanous types can simply grab the on-line image and use googlemaps to find out exactly where this nice shiny bike lives, and maybe they'll pay you a visit in the middle of the night with a van and relieve you of your pride and joy... :'(
Best thing to do is turn off Location services, or go through the steps listed in the TDR thread prior to posting, or just use a regular camera to take the photo in the first place.
