I would be very surprised if Google is not data mining everything they can, it's always been their main business model.

With the photos it could be as simple as merging the meta data from those photos together with a user profile for even more targeted advertising.

Somebody making a lot of photos of certain things might be more interested in buying these things.

I'm pretty sure the real data wizards can think of quite a few more, and better, ways to monetize such data, particularly at the scale that Google is collecting it.

I believe they can't do that without explicitly stating such usage of data in terms of service.

Very well paid teams of lawyers have spent considerable time and effort writing these terms of services. In the case of Google there is so much of this stuff, for all the different services, that Google doesn't even have a single conclusive ToS document, but instead a whole website [0]

Good luck finding anything explicitly stated in there.
