Disable right click for images only

Hi,

Is it possible?
And how to achieve this w/o alert window.

The ones that I found on tips&trick section is disabling right click for everything.

Thank you.

Not really sure this can be done sorry

Okay so I disabled right click for all..
But where should I put it so it would be active in every page?
currently it's only at the main page since I put it under the homepage message..

I mean, the script doesn't work if I change pages..

I've also tried by adding the code to the widget and it won't work at all..

Put it in an announcement, and make sure that the announcement is on all pages.

Thanks slg!
problem Solved!
