MailPictures is a plugin for Apple Mail which allows your image to show up in your messages This little plugin has been around since Jaguar (OS X 10.2) and now updated for Tiger. It extends Apple's idea of putting the little thumbnail of you in the upper right-hand corner of your messages to mail you send to non-Mac users. You don't need to do anything more than install the plugin to let the whole world see your ugly mug. I haven't tried the Tiger build, but I'm hopeful!
