jQuery: Prevent Right-Click on Website

Sometimes we want to prevent the user from right clicking on our website. With this small piece of code and the help of jQuery, you can simply avoid that the context menu opens when the user right clicks on the page:

$(document).ready(function() {  
   $(document).bind("contextmenu", function() {  
      return false;  
   });  
});  

Of course, also this code cannot prevent effectively, that someone can save the images or something else from our website. First of all, it only works with activated JavaScript and secondly, there are other possibilities to save images then to use a right click. But users who are unaware of what they are doing, can be certainly deterred.
