Q: can I see pictures rented or bought with subtitles

Some but not all movies have closed captioning, study the preview page at the point-of-purchase to discover whether a movie has closed captioning or not.

Yes, it is the screen where you choose to purchase or rent and you also see a description of the movie along with a lists of actors etc etc.

If a movie has closed captioning, it has the closed-captioned symbol, which is simply twosmall c's (cc)

Yes, you can turn closed captioning on and off at settings> audio and video> closed captioning.

I can't be certain, I don't use closed captioning, but understand its more for the hard of hearing rather than different languages, so may well only be in English.
