yeah I know and even that doesn't stop people but if I see one of my photos
used somewhere important like a magazine or photography contest etc. then there is no doubt about the plagiarism
and infringement on the copyright. We have to take into account those with bad eyes! LOL
I do understand how you feel, as I've got several images
that I've sold numerous prints of.
Truth is though that the legal copyright is *implied*, meaning
if you have the original artwork including EXIF data, then you
can easily make your case in a court of law. There's technically
no need to place our © on the image itself.
Did this for illustrative purposes only, but if someone wants to
use one of your pics the © mark on it means very little. Removing
your mark took me less than a minute per pic.
If someone does steal one of your pics, then a "Cease and
Desist" letter can sure get their attention. Had an environmentalist
site heist one of my landscape shots, and I gave them the choice of
paying me a royalty to use it, or take it down. It was gone from their
site before the day was over.
