 Sending photos to girls can be very useful in an interaction. It can build comfort, create connection, make you seem more real than words on a screen. It can also be used to communicate your personality and/ or values. This example shows the girl something he has. From that photo she can infer that he has money if he is living in an apartment like that. 
Her: I pretty much just stay in my bathrobe all day
Her: and go to meetings like that
Her: Unashamed haha

Haha damn that’s hot(Sent photo of the view from his balcony)I don’t think I’ll ever get sick of this view
