A little Off-Topic
To prevent your photo to be stolen by some Tom Dick Hairy, you
are advise to put the copyright tag next to the bus closely and not
the bottom of the picture. Or best, putting a translucent tag
which should
cover the entire picture or object.
If you are comfortable with people using your photo(s), like
editing, claiming that that photo is his/hers after cropping out,
you can don't do it. 
OT: Tom Dick & Harry not Hairy LOL
