Mapping String to image

Hi all,

I want to send an Emoticon (image) to a user in my instant messenger. I have the statement (chat.sendMessage) for sending the message. But im not sure how to link the text to fire the image. Example:

user types.... :) and smiley.jpg gets sent.

How do I make the link ? can some one show me how?

Thanks Dilip
