Using adobe's JPGEncoder (com.adobe.images.JPGEncoder) class and ByteArray is pretty much all you need. Converting image to byte array (assuming CAPS are variables you'd need to fill in):

// -- first draw (copy) the image's bitmap data
var image:DisplayObject = YOUR_IMAGE;
var src:BitmapData = new BitmapData(image.width, image.height);
src.draw(image);

// -- encode the jpg 
var quality:int = 75;
var jpg:JPGEncoder = new JPGEncoder(quality);
var byteArray:ByteArray = jpg.encode(src);
