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 press the Print Screen key to capture the image. Or they press F12 in some browsers and get the image URL very easily. In the end, visitors already have every image on their disk anyway, because browsers cache everything they display. The only people you inconvenience are visitors who want to open links in a new tab or use the context menu.

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 :)
