Does anyone know how to change your avatar of your profile
Click that link. It won’t work for anyone else but you, the stuff you need is on that page.
After that check the “I will upload my own picture:” box/circle and then hit “Browse…” and select a picture 200x200 pixles or smaller. I suggest if you want the biggest that will still look good 200high and 130wide.
If you have a picture that you want cropped/scaled I can do it for you.
