In iMessages no Profile Picture is sent.
What appears in Messages at the other end is dependent on what that persion has for your Pic in their Address Book/Contacts app.
Outgoing Messages look like they send a Pic (my "Ralph" sig pic) but it is not sent.
The sync from the iPhone shows the My Card pic from the Contacts or Address Book app.
My wife's address Card does not have a pic.
