In computing, an avatar (also known as a profile picture or userpic) is a graphical representation of a user or the user's character or persona. It may take either a two-dimensional form as an icon in Internet forums and other online communities or a three-dimensional form, as in games or virtual worlds. Avatar images have also been referred to as "picons" (personal icons) in the past, though the usage of this term is uncommon now. An avatar can also refer to a text construct found on early systems such as MUDs. The term "avatar" can also refer to the personality connected with the screen name, or handle, of an Internet user.
