It’s a simple enough question, and one we hear a lot: How can I watermark a photo?
Although there’s no sure-fire way to stop people from stealing your photography on the Internet (or words for that matter), it’s your prerogative if you want to include watermarks. But before you do, be aware…
A good read about watermarking photos. I’m on the fence about it. I would prefer a metadata watermark of some kind, but I don’t want to pay to do so. It would be better if camera manufactures embed this into the photos their cameras take automatically and if computers required this information just like a filename.
