Advice for a newbie on sharing/trading photos

[TubaMan2018]

Hi all. I'm trying to trade some of the photos I have with another member here. His English is not perfect. Here is what he instructed me to do: "Most of the traders here use web pics. Like to see some real and new. I will send back when i get PN."

Can anyone help me understand what he's asking me to do here? Sorry for the probably very basic question!
