How to block changes of desktop background image

I manage a 30-computer Mac lab in a public high school and I would like to prevent users from changing the desktop background image.

As far as I know, there are two ways to change the desktop background image: through System Preferences and by right-clicking an image and selecting Set Desktop Picture.

Blocking System Preferences is easily done through Parental Controls.

But how do I prevent the right-click, Set Desktop Picture method of changing the desktop image?

You can imagine the kinds of images that end up as desktop backgrounds in a high school computer lab. 😁

Mac OS X (10.6.8), iTunes 10.4

You might try going to System Preferences > Keyboard > Keyboard Shortcuts. In the left pane select Services, then uncheck the item "Set Desktop Picture" under Pictures in the right pane. Once that's done, block that prefs pane.
