My profile in the bottom left, followed by Avatar. Not the profit editor associated with the Howdy link top right, but the My Profile link bottom left.

Theo Neeskens said I see some people have a profile picture, but I can't find where to change / upload a picture. Help?

Hi Theo, on your profile, you have some "edit avatar" option. If you have a very small picture file, you can upload it here.

Thanks guys. I was looking in the "Howdy" profile.
