Have a good read of Henry Jones - Using the AS3 Jpeg Encoder. He explains exactly what you need, plus some!

You basically what to use the BitmapData class to convert you displayobject into image data. Then you can use JPGEncoder from AS3 Core Lib, to encode that data into a JPEG. Then with a bit of serverside code you can send that JPEG to that server.
