It's not like we are at the mercy of image thieves - there are ways to deal with copyright breach and image theft -
1: Register ALL your images that go to clients or go online with the U.S. patent and copyright office;
2: Sign up with an reverse image search such as
http://www.tineye.com/ ;
3: When your images are stolen and unauthorized use is discovered by Tin Eye, demand payment from the infringer;
4: If they refuse or offer a fraction of the standard use rate, consult an attorney;
5: Have the atttorney file a lawsuit for copyright infringement, drag the thieves into court and break their balls; collect usage payment, plus punitive damages, plus attorney and court fees.
Some will say "I don't have the time to do that." That's where the attorney comes in to play. He/she are the ones investing their time on your behalf. Hire them, let them do their job, and somewhere down the road you will be compensated by the thieves, who will also pay your attorney.
The vast majority of people do not accomplish #1, which prevents them from accomplishing #5. The way judges look at copyright infringement seems to be,
"If you don't value your work enough to register it with the U.S. copyright office, you are obviously not a professional photographer; why should I take your claim seriously if you don't take your own work seriously??"
It's hard to argue with that line of thought.
Without registration, copyright infringement is
still a crime. The only satisfaction you will likely get is having an attorney send the theives a "knock it off" letter. Without copyright registration of your images, you cannot file a copyright infringement lawsuit; an infringement lawsuit over unregistered images will be tossed out by a judge, if the attorney even files it to begin with.
We do in fact have options when our work is stolen, IF it has been registered. If a photographer doesn't value their work highly enough to spend a bit of time registering it, they don't have much room to complain when it is stolen, do they?
We know there are image thieves out there. Protecting your work is necessary in today's world. It's just a matter of taking personal responsibility for protecting your work.
