On a forum, an avatar is a display picture that will always settle among poster's names in their posts (either on top, on the side, or on the bottom of it). On MFGG, avatars are placed under the poster's name, followed by their custom title underneath.
Currently, the maximum avatar dimensions are 142x160 pixels, although the limit was once 200x200. A custom MFGG base avatar gallery has also been considered, but it wasn't implemented until the phpBB forums first opened. The gallery includes sets of avatars featuring art from assorted Mario games, as well as some of Thunder Dragon's sketches.
