QQ avatar is the virtual image of QQ, a chat software developed by Tencent. It was originally designed by cartoon characters. Later, with the upgrade of QQ version, it gradually evolved into an avatar that can be designed by individuals, which can be any picture such as your own photo and favorite star figures. The size is generally 40×40 pixels. In addition to its own QQ avatar, in August 2009, Tencent opened all QQ users to upload customized avatars. QQ users with QQ level 4 (January) and above can upload and change their favorite avatars at will. Users with QQ level below level 4 can change their personalized avatars at will within three days from the date of uploading their customized avatars for the first time! Tencent also launched a dynamic avatar for QQ members to use.
