Sure follow me step by step okay

1) go to the top, on the left of your screen you will see "User CP" click on it
2) Look to the left of your screen, you will see "Your Control Panel" on that list you will see "Edit Avatar" under Settings & Options, click on it
3)Now you can either get your avatar from your computer, in which you browse the file
or you can paste the url
4) then click 'changes' and then your avatar picture should show up...if it doesnt try again, if it doesnt again, then let me know okay
