By posting pictures of myself, I am also broadcasting the message, “It’s ok to be photographed even if you are not a model.” This may subtly influence people to post their own pictures; as a result, they will become more aware of their own image. As a result of that, they may learn to accept their unique physical traits as just that — unique traits — instead of flaws to be hidden.
