Thank you both. Now deleted upside down avatar. I'm using an IPad.
Looks like I'll need use my PC for this site?
But still don't know why it was upside down.......hope will be okay on PC
Cheers.

If you're trying to do it from a smart phone or tablet using the app, you may not be able to. You need to go the the web site.

Go to top left where your name is and select account.

There the option to use custom avatar needs to be checked.

Make sure its unchecked and select ok and poof your avatar is gone
