I took the screenshots, so they are mine but obviously all rights are owned by the animation studio, dude. Also I can't get sued because I'm doing fair use, you can look into that. Moreover, it clearly states screenshots from the film.
P.D: What I mean is that I didn't take the images from other sites, I made the screenshots myself.
I know what you mean, but I've seen anime studios reporting facebook profiles for using screenshots in their review posts. They are not very nice. Film studios do not care much on the other hand.
I'm not bothered here personally, if not slightly amused.
I've seen these cases happen when they post screenshots of films that haven't yet come out on Blu-Ray and are still in cinemas, they do it so people don't get spoilers and don't want to go and see the film. Your Name has been out for years, I don't think there are any problems.
