If you use Opera's super fast e-mail or news client, you also get access to a new Contacts panel (which is otherwise hidden by default). The Contacts panel gives you an easy interface for keeping track of everyone you interact with via chat, e-mail, and newsgroups. Simply navigate to 'Tools->Contacts'. The Quick Find makes it easy to track someone down, but Opera lets you go one better. Right-click a contact, select Properties, then Images. From here, you can choose a picture to associate with that particular contact, either an icon from the list or an image from the Web.
