Your Profile is Hidden to make your avatar visible go here http://pulse.yahoo.com/y/settings click Manage Privacy Settings.
Move the second tab so it says Your profile is currently visible.

AVATAR

At this time you can not make a avatar from a mobile device, perhaps that will change in the future.
For now profile changes must be made from a computer.
Go here , http://profile.yahoo.com top center put the arrow on your avatar, click change picture.
From there you can upload a image from your computer or import a picture from facebook. When finished click submit on the next page.
Go here to make a Yahoo Avatar. http://avatars.yahoo.com/

If you want a custom avatar go to one of these sites and make a custom avatar, save it to your computer and upload it as a picture.
