An avatar is an online representation of you (i.e. a picture used to identify you to the community). The default avatar for all users is a small silhouette/shadow of a person. Your avatar appears next to all content that you contribute to the community. If you would like to change your avatar, you can upload any picture that you would like. Note that a picture does not necessarily have to be a picture of yourself – for example, it could be a picture of your favorite car, or actor, or travel destination.
