In your profile, click on the current picture (the one that starts out looking a bit like a faceless head on shoulders, in pale grey). Under that is a label "Edit avatar"; click that. A window should open, titled "Edit Profile". In that window, click on "Upload an avatar". A dialog box should open to let you select a picture from your computer. When that picture has gone from your computer to the window -- that is, when you can see it inside the "Edit Profile" box -- click on the "Save, I'm done" button.
