Bro, don't bother, buyers with a lot of non-specific questions 95% of the time not serious. Just buttering you up and wearing down your patience with questions so that you invest time in them. Then inevitably, they will sometimes wait a few days, ask questions here and there, then pop the "can the price be negotiated" or "give discount?".
So you're better off just not entertaining them. The moment they sense they're not going to get their way, that's when they say this sort of thing to see if you're weak and will give in.
I don't even bother answering non-specific picture questions anymore. Usually I provide quite a good description and set of photos. ANyone who asks more usually is a deal hunter.
