I am trying to make edits to page on a living person on behalf of said living person. He would like to change the photo.

Welcome to Wikipedia. I can talk you through the process of doing this. To start with, you should let me know which person and what photograph. If you'd prefer to handle this more discreetly, I would suggest contacting OTRS where our Volunteer Response Team will be glad to assist you. Cheers, Bovlb (talk) 17:55, 20 February 2019 (UTC)Reply

Thanks! Will handle more discretely.
