There are a few methods to protect content: One is CSS and another one is the Javascript method.
It is better if you add both methods.
Methods include:
Disable Right-click
Disable selection
Disable copy
Adding an overlay on the image. So that images cannot be saved easily... etc...
Of course, nothing is foolproof, but it will definitely steer away majority of the users and also webmasters too, as most of them really haven't learned the basics yet!
Please search google for codes. They are easy to find. Make a list and use them.
The code embedded by the above plugin on each page is unbearable. If it was not, I wouldn't have complained.
