Filestream.write for .jpgs

Question

Hi,
i am working on an AIR-Project. The User can load pictures from his computer into the Air-Project. What I want is, to save these pictures automaticly at a certain Folder. I need that because the next time the user is using the Program the picture shall be seen (so i have to have it in a certain Folder)
I just learned how to create a new document in a certain Folder:
import flash.filesystem.FileStream;
import flash.events.Event;
import flash.filesystem.File;
import flash.errors.IOError;
var fileStream:FileStream;
fileStream = new FileStream();
fileStream.addEventListener(Event.CLOSE, fileCloseHandler);
fileStream.addEventListener(IOErrorEvent.IO_ERROR, fileIOError);
var writeFile:File;
writeFile = File.documentsDirectory.resolvePath('AIR/test.txt');
fileStream.openAsync(writeFile, FileMode.WRITE);
fileStream.writeUTFBytes('Hello World');
fileStream.close();
function fileIOError(event:IOErrorEvent):void
trace ("Sorry did not work");
function fileCloseHandler(event:Event):void
trace ("DONE");
So far so good :-)
All the Examples i found creating a (.txt) text-file where the content was set by:
fileStream.writeUTFBytes("Hello World');
Now i have 2 Problems;
1) as far as I understand I need to change from "writeUTFBytes" for text-files to something like "writeObject" or "writeBytes" to stream .jpg data - right???
2) the bigger Problem - I do not know how to let my graphic.data be the content instead of the "Hello World"
What i have now does work in parts - the first part loads the picture "pic.jpg" / and the second part is a version of the code above that worked well for a .txt
What does not work is, that I do not get the content of "graphic" into the file to be streamed...
Here is what i have;
var graphic:Loader = new Loader();
var url:URLRequest = new URLRequest("pic.jpg");
graphic.load(url);
graphic.contentLoaderInfo.addEventListener(Event.COM PLETE, done);
addChild(graphic);
function done(evt:Event)
trace ("loaded");
import flash.filesystem.FileStream;
import flash.filesystem.File;
import flash.events.Event;
import flash.filesystem.File;
import flash.errors.IOError;
var savethis:File = new File();
savethis = graphic.data;
var fileStream:FileStream;
fileStream = new FileStream();
fileStream.addEventListener(Event.CLOSE, fileCloseHandler);
fileStream.addEventListener(IOErrorEvent.IO_ERROR, fileIOError);
var writeFile:File;
writeFile = File.documentsDirectory.resolvePath('AIR/pic.jpg');
fileStream.openAsync(writeFile, FileMode.WRITE);
fileStream.writeObject(savethis);
fileStream.close();
function fileIOError(event:IOErrorEvent):void
trace ("Did not work");
function fileCloseHandler(event:Event):void
trace ("good work");
Hope you can help me with this!!!
Try to keep you answer simple - i am not an every-day flasher (looks like I am getting there :-))

I'm having the exact same issue.  I purchased Aperture recently just so I could edit the metadata on lots of old jpg pictures and scans.  Until I upgraded to Lion, it was working well.  Now with Lion, I can still edit the metadata, but I cannot write the metadata back to the master.   I just spent the last two days filling out the metadata info (primarily Title and Caption), figuring to save to master once I got done with the batch of photos I'm currently working on.  I don't want to lose my work. 
I'm wondering if I can accomplish the same thing by exporting my updated metadata versions and reimporting them.  Might that work?  Will I lose/gain anything in the process?
