I was interested in learning how to copyright my photos so that they can't be saved to another person's computer without my permission. Can someone tell me how to do this? I'm not talking about a watermark. Thanks.
It is not copyright either.. Copyright is registered with the Library of Congress to establish ownership, but it does not prevent any action by anyone. However, if registered, copyright does allow you to go to court for damages.
We have copyright simply because we created it, but to go to court requires registration.
A photo on the internet is always vulnerable. If you have to put it on the web, I'd say never post one full size, which is not useful on video anyway. Make the images be small enough to not be very attractive to those that may want them. This smaller size is still usable on computer monitors though, and some consider anything on internet to be fair game.
I am ignorant about many details at this forum, but here, I do think if you put them in the gallery here, then the forum will prevent clicking actions on them. Go to the gallery and Right Click on some to see this. That will prevent some access, but nothing is failsafe, it just takes smarter thieves.
