Can "da- words" be used for humans as well as objects?

Question

I was speaking to a friend of mine about another person and I almost used "davon" to refer to a human. Is this allowed? For example: I realise it is legal for the following to take place: > Ich hab ein neues Auto. > Hast du Bilder davon? In the above example, I used davon to refer to an object, but can I refer to a human in the same way? > Kennst du meinen Bruder? > Ich bin nicht sicher. Hast du Bilder davon? I hope I have articulated my question clearly enough but if not, my apologies in advance.

Answer 1

The correct question is:" Hast du Bilder von ihm?"

Answer 2

No. You would have to say "von ihr" or "von ihm."
