Show off a favourite picture while you IM.
You can use an image to represent you when you talk with friends on Yahoo! Messenger. Select a photo from the display image gallery in Messenger, or browse your computer's hard drive to select an image. The following types of files can be used as a display image: PNG, BMP, JPG and GIF.
Your display image appears next to your name in your friends' Contact lists, so they can easily find you by your picture, or your name. It also shows up next to you in the IM window during a conversation. When you update your display image, it automatically updates on your friends' lists too.
Looking for a new display image? Just search for an image on Yahoo! Search. When you find one you like, save it to your desktop, then load it into Yahoo! Messenger.
