title: Socket.io chat app that can also send image and even file
body: <p>I've been interested in the <code>Socket.io</code> project recently and I wonder if there's easy way to send image or even other type of files without having to use other library. I'm not trying to upload the file to the server to store, I just want to broadcast it to those who are in the chat room at that moment. So the code should be minimal. However I'm really bad at encoding/decoding stuff, so some example code would be great.</p>
