My profile picture is going to be Sonic wearing glasses but I don't know how to put in the profile picture! Can someone please help?
Hey and welcome! You should be able to change it on this page, under the first section "Personalized Picture".

Then you can specify whether you would like to use the picture from a specific URL, or just browse and upload it from your computer.
