Well I would like to copyright or digitally protect my photos what software do you need to do this ?
Now if you have your pic watermarked is that legally sound from keeping someone else’s hands off or can they still use it?
Best watermark software to use ?
Might help if you tell us what you're trying to "protect" your images from or how you're using them that is causing you to ask about extra protection.
If you're posting images online there is no software that's going to protect you. None. Post them online and someone, somehow can get them. Period. End of discussion. If that's a major concern for you then I would suggest not posting anything online.
