What can you do to protect your images?

Scammers will steal whatever they can, and that includes photos of real people.  To stop them stealing yours, watermark them.  Not just a small one in the corner.  Make it a big watermark that’s impossible to crop out.  If you run a website, add the URL to it.  If you have twitter, add your name.  The harder it is to steal, the less likely they are to.
