Facebook- putting profile pic as smiley on chat

[KEN]

First get the Id of the profile..if you dont know how to get the id part then read through this topic and you will find different ways of finding the id of a person..http://sethioz.co.uk/forum/viewtopic.php?f=47&t=1024

Now in the chat simple type [[Id number]] and it will send a small version of the profile pic of the id you wrote.
You can search on facebook for 'troll face' or anything else and send their id number as to make a troll smiley..
