You should click on your profile (to be found on the top line of the page). Then click on "edit your profile". There you find a window in which you can put in your personal avatar. You need a direct link to a picture placed on a website or webspace, if you want to put in a picture available by yourself. You also can click on the link in the avatar-field, that opens you a broad collection of pictures. If you want to take one as your avatar, just copy the link of the picture and paste it in the blue field in the avatar-field of your profile. If you want to save the changes of your profile, click on the field "update" on the bottom of the profile page.
