Yahoo! Messenger offers a feature called as “Avatars” which is a type of image created by someone who is using yahoo! Messenger to represent himself or herself in an attractive manner while chatting with friends. It can be modified according to the choice of a user and he/she can change the hairstyle, accessories, clothes, etc., of their Avatar. It can also be used to express the mood of a particular user. If a user is sending a smiley emoticon in a message, then his/her Avatar will also smile along while sending a message.
