disable right click

Hi
How to disable right click when the image opens in a modal window .
I have pictures in the text of the page that open in a modal window and I would like to block the possibility of copying them
All add-ons and scripts that I try block the entire page, but not the modal window

Hi
I don't have this feature and to be honest this is totally useless
You can save any image that is displayed in the browser, even with right click disabled
CEd

I know . despite this, 90% of people who accidentally visit a website can't do it, save a page or image when they are not right-clicked. I want it to be a simple difficulty. Nothing more

I saw this function in some gallery component for Joomla.
But I personally don't have enough knowledge (javascrypt) to understand exactly which code fragment is responsible for the modal window.
I can do it for the whole page, but not for the pop-up window
ok, benda tried again, maybe I'll come up with something finally.
update:
And I solved the problem. Topic to close.
