what does it mean when a guy sends you pictures of what he's doing

Of course! I'd love to hear your question.

Hmm, it often means he's trying to share a part of his life with you. He wants you to be in on what he's doing, or just wants to make a connection with you. But remember, it's all about context. It's different for everybody and every relationship.

That can be tricky. If it's just every once in a while, he might just be being friendly. But, if he does it frequently and he is genuinely interested in your response, then he might have more feelings. However, the only sure-fire way to know is to ask him directly.
