Is there a way to disable right-click on Livejournal posts?

I need to protect drawings from art-theft on a private livejournal community. These drawings will be posted as journal entries. Is there a code to disable right-clicking (and thus copy/paste and 'save image') on LJ posts?

Perhaps if it allows user input javascript, but there is a way around this so it's not much use. Not only can you disable javascript in the browser to get around it, but you can also just copy the image location from the website source code. Open the image directly and save it from the image itself, bypassing the script altogether.

There are more websites out there with their own variations of the script in the two links above.
