Why do guys randomly send you a picture then get dry and end the conversation?

I've had two guys do something like this. Basically, they don't talk to me for a few days, then randomly send me a picture of a beautiful sky or something like that and when you try to talk to them they get dry and the conversation ends somehow. Why do they even send me that picture in the first place?
