Add avatar image. Start by uploading an avatar image. Just click on the avatar that shows a camera icon to "add an avatar." You'll be prompted to upload a photo or to take a photo with your webcam.
Edit your profile. After you have added an avatar, your avatar photo will now appear in the upper right-hand corner of any Twitter webpage. To access your profile, click on your avatar in the upper right-hand corner and select "view profile." Then click on the Edit Profile button to finishing editing your profile.

When you are done entering your profile information, press "Save."
