I'll try Runnybeak. You go into your account settings. On the top right of the page you can see, there's an down ward arrrow. Click on that and you'll see some options. Click on My Settings. This will take you to another page.
On the left hand side, you'll see the faceless T- shirt boy, click on Edit
On this page you will see Change your profile picture. You will have to click Browse. Then you can pick the picture you want. All the avators are small so too big an image wont work.
Do you have a pic in mind and is it on your pc?
