I can confirm the current behaviour is to fetch the Google avatar whenever you log-in via Google, so you should change it there.
Thank you.
I see that could be a bit annoying, maybe we should change it so that it only happens for users who registered via Google in the first place?
At least make the behaviour clear. At the moment the profile makes no mention of the behaviour, it just says that I can upload a photo, there is no mention of it being overridden by anything from Google.
