Help me (my avatar)

I want go get a avatar but it keeps saying "The URL you specified is invalid" help me.

1) get photobucket (app)
2) find a 90x90 pic (it can be smaller but NOT larger
3) download the pic into photobucket
4) go to the setting part of that pic
5) use the URL that they give you

then you can paste it here and all will be A-ok

It worked, Thank you!
