Unfortunately for you guys, I don't think it's a matter of informing them up front. It's a great idea and the few who respect it, it will help. The real issue you are dealing with is respect for your work. My guess is 95% of the people stealing your work will do it whether warned or not and only take them down when asked. I'm on your side but a tough battle.
People steal our tuning all the time. Unfortunately, we really have no recourse at all when that happens.
I disagree, It is a photographers responsibility to inform the customer what they can and cannot do with photos that the customer is purchasing. The first card anyone ever plays when it comes to copyright infringement is the "I didnt know" Card.
I shoot onsite at events and run a sales booth, I print everything out onsite while they are waiting. On my table posted next to the customer viewing monitor is a "Terms of Purchase Agreement", also when they get their prints from me, as I of my employee is putting their photos in an envelope, we inform them that included in the envelope there is a "Terms of Purchase" agreement in their that states what they can and cannot do. And I or my employee also inform them that along with that purchase agreement that options to purchase digital negatives, limited use web images, and additional prints, for commercial and other use are also on their, as well as my full contact information.
The thing I have going for me is that I have a pretty set customer base, as I see a lot of the same people over and over. But even with new customers, I have my basis covered and my customers are informed, that way if they do break the rules they cannot play the "I didnt know" card.
And it seems to work. I also sell strictly Images for Facebook for a cheap price, the stuff is watermarked of course.
One thing I started doing this year and it cut down on most of the theft from my website. Everything that I put up now a days on my website (not facebook) I have a big watermark over the whole photo, and it states that the photo is copyrighted, and if this image is seen outside of my website please report it and it has my email address. Since I started doing that I have not found a single image of mine taken off my website. I also have disclaimers everywhere and they have to enter their email address to enter the galleries.
Now one thing I have done and its easy for me since I have a pretty set customer base, is I go and take every print that I sell, and I crop it down to 72 dpi, I water mark it, and include "Facebook Use Only" and I upload a customer print album on the Facebook of the Organization that I shoot for. And I inform my customers of this when they buy prints, and I also explain to them that the images I put up on Facebook is to say thank you to the customer, and that the images are only to be used on their Facebook and no other site, or any commercial use. Doing so has cut down dramatically on the amount of people who take a picture of the print , because usually most of the time they are taking pics of the prints just to post on Facebook.
