A lot of pictures have what they call, Metadata and these scam ICO's do not even know how to strip the Meta Data from these pictures before they use them.    Metadata is called Exif (Exchangeable image file format) and is a standard that specifies formats for files recorded by digital cameras.

GPS metadata can actually tell you where the photo was taken, and this might help you to narrow your search. Most profile photos are taken in the area where you live.
