Saving snapshot in a sharedobjects?

hey guys does anyone know how i can save a photo taken from a webcam and save and retrieve it from a shared object??? i dont have php server so throw that out of the window

so far i got the snapshot working, here is my script

motionTrack._visible = 0

output_vid.attachVideo(Camera.get());

import flash.display.BitmapData
import flash.geom.Matrix

var snapshot:BitmapData=new BitmapData(x=155,y=120);
var snapshot2:BitmapData=new BitmapData(x=155,y=120);

function takeSnapshot(nr)
{
snapshot.draw(output_vid,new Matrix());
}
function takeSnapshot2(nr)
{
snapshot2.draw(output_vid,new Matrix());
}

pic.pic2.attachBitmap(snapshot,1);
another.attachBitmap(snapshot2,1);
main.game.face1.pic2.attachBitmap(snapshot,1);
main.game.face1.another.boss.attachBitmap(snapshot2,1);
