There are actually up too 3 methods that I know off that work very well and are as simple as right clicking. However I shall not say how to do this as the reason those pictures are protected are because of copyright.
You should not ask Questions on how to steal copyright pictures and everyone providing answers are equally in the wrong here. If you need to know how to steal these pictures it comes down to common sense and sadly is very easy to do so. My advice is to play and find out for yourself and keep your Computer Forum membership in good standing.
