Google removed that functionality because of a settlement with Getty.
Edit: Come to think of it, if it's on my device, it's already saved in some way, shape and form. Clearly nobody technical at that company made that decision to sue Google.
What Google should of done is offered to advertise that an image is available to purchase...
Unfortunately the law often does not make objective sense. And even when it seems to from your perspective, the way others interpret it does not.

Technical people can be arseholes too you know. Many patent trolls are technical people, not just legal eagles, for instance.
This isn't about the law. It's unclear if the law would require something like this or not. Google decided not to find out by settling. The settlement terms were up to the two companies to decide and were not mandated by laws.
