Here you go. Hope you like it. This is what you have to do:
Right click with your mouse on the avatar below. Then go to "Save Picture As." Save it onto your computer.
Then go up top on YT and go to "user CP."
Then on the left go to "edit avatar."
Click browse, and find the avatar that you just saved onto the computer.
When you find it, click "save changes" and then it should be up.
