Can you send picture message using a Windows Live Messenger API/SDK?

Is there a way to send a picture message via a Windows Live SDK/API of some sort, to one of your messenger contacts?

I've been searching for about an hour, and seen mentions of some REST web services, and oAuth being the way to do it.

Could anybody point me in the right direction, or give a quick code example, as I have been searching for a while and coming up with nothing.

Closest I found was a Windo开发者_如何学Gows Live SDK v4.1 that contains a single DLL

Microsoft.Live.AuthHandler.dll

Any help on this would be greatly appreciated.
