I believe that only the Duotone and Monotone themes have the ability to disable right click. That being said, I want you to know that using it creates a false sense of security. It takes no skill at all to search the internet and defeat it in seconds flat. I know this because I’ve done it to prove it to myself.
I believe what I said is true but it’s not new and if it proves that I’m wrong I’m not worried, as I’m sure that you know who will set the record straight, while I laugh and pass the popcorn.
They didn’t add that feature to the themes. The way those two themes are designed, if you click on the right hand side of the pic, it goes to the next picture. If you click on the left, to the previous. So you can’t right-click on any but the left hand side of the very newest picture. It’s an accident.
