The rightclick "disabler" is possible to go around aswell, so it's not a disabler in it's true sense, more like a thing to make it alittle harder, so a CSS that mess up everything like Connorhd said, would probably do about the same in 'disabling' ... remember, everything you can see you can save ... if it requires looking in the cache, disable certain scripts (adblock functions and such can block java and stuff) or something else ... it's really a thing that will make it a bit more work for someone ... but in the end, far from really disable the possibility to save images, or other things.
