We have an interesting trick for all our Facebook readers. And the trick is to use your own or any of your friends’ profile display picture as a smiley. Yes, you read it right. At the end of this post you will be able to shock your friends by sending anybody’s profile picture as a smiley.
To do that, navigate to the profile of the person whose image you want to use as a smiley. Copy the profile id from the browser URL. Say for example, http://www.facebook.com/profileid is the URL. Then you would need to copy profileid. Now, get back to the chat window and type [[profileid]]. I repeat. Open two square brackets followed by the profile ID and then close two square brackets. Hit Enter and see the magic happen! Go on, surprise your friends.
