Disabling Right Click to save pics

Hey again, quick question if I may.

I have it set up as to where no one can download a pic by right clicking it, but mobile devices can still save a copy of images.  Does anyone know a work around for that?

Thanks in advance

I can save your images if you have right click disabled or not... any one can, by looking at the source code of the site.

You can also copy the entire page and cut the image out in your favorite editor as well. If it's on the web, it can be stolen.
