The limits of cars, tunes and paints have all been doubled (and you can still only have one paint/tune every two cars, but 2000 files would probably completely kill the already very unstable game), but photos are still a very random 66 (which is also a profane number according to both Forza and Xbox itself; check it).
It’s a pathetically low number if you’re a fan of taking pictures, and it’s very annoying needing to delete one picture every time you save another one.
Even if it’s doubled there’s still only enough space for one picture per 15 cars if you had a full garage, but I don’t think you’d be taking a picture of 2000 cars and 132 is quite a big (and random) increase.
