This component does not feature the ability to prevent right clicks and I will not implement any magic right click prevention in the future. It does not help in any way. Users can simply hit the PRINT key to get the image. Or they press F12 in some browsers and get the image URL very easily. In the end they already have all the images on their disks without doing anything since browsers cache the images you see in front of you. Only users who like to open sites in a new tab or use the context menu in any other way are handicapped.

If you really need something like this just check the JED for plugins. There are a couple of options. But in the end the only way to protect images is to not upload them :)
