Cool, but everything in the right-click menu can also be found in the 'edit' or 'view' menus.

 

Simply type this : oncontextmenu="return false"

for example : <img id='img1' oncontextmenu="return false"/>

this will disable right click on the image.

this works for me.

 

Only from right click you can not stop to seeing or copying site.
