Where are the photos and username change

Been a while. Where are the photos and how do I find photos I previously posted? I’d also like to update my username?
Please advise?

I’m not sure about the old photo section from the old site. But your username is configurable by

  • clicking the avatar in the upper right with your initial

  • then click your name from the menu that extends down

  • then click preferences from the next menu.

  • username is the first option
