How do you feel about receiving pictures via text, with no context?

I have a family member who does this.

For example: might send a picture of a car, their childs school pic, etc.

Why not send a caption? I.e
" look, it's his preschool photo".
" do you like my new car?"

I don't like receiving pictures with no context.
It's like you're fishing for compliments or want ME to start a conversation, which I'm not about to.
