Im loading images into Flash and using JPGEncoder to encode the image to a ByteArray and send this to AMF PHP which writes out the bytearray to a file. This all appears to work correctly and I can download the resulting file in Photoshop CS4 absolutely fine. When i try to open it from the desktop or open it back in Flash it doesnt work... Picasa my default image browser says "Invalid"

Here is the code i use to write the bytearray to a file -

```
$jpg = $GLOBALS["HTTP_RAW_POST_DATA"];
file_put_contents($filename, $jpg);

```

That's it ... I use the NetConnection class to connect and call the service, do I need to say Im sending jpg data? I assumed that JPGEncoder took care of that. How can I validate the bytearray before writing the file? Do I need to set MIME type or something .. excuse the slightly noob questions, a little knowledge can be a dangerous thing.

Thanks

Here is some code -

1) load the image into Flash player

```
item.load();
function _onImageDataLoaded(evt:Event):void {
  var tmpFileRef:FileReference=FileReference(evt.target);
  image_loader=new Loader  ;
  image_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, _onImageLoaded);
  image_loader.loadBytes(tmpFileRef.data);
}
function _onImageLoaded(evt:Event):void {
bitmap=Bitmap(evt.target.content);
bitmap.smoothing=true;
if (bitmap.width>MAX_WIDTH||bitmap.height>MAX_HEIGHT) {
  resizeBitmap(bitmap);
}
    uploadResizedImage(bitmap);
}
function resizeBitmap(target:Bitmap):void {
if (target.height>target.width) {
    target.width=MAX_WIDTH;
    target.scaleY=target.scaleX;
} else if (target.width >= target.height) {
    target.height=MAX_HEIGHT;
    target.scaleX=target.scaleY;
}

}
function uploadResizedImage(target:Bitmap):void {
var _bmd:BitmapData=new BitmapData(target.width,target.height);
_bmd.draw(target, new Matrix(target.scaleX, 0, 0, target.scaleY));
var encoded_jpg:JPGEncoder=new JPGEncoder(90);
var jpg_binary:ByteArray=encoded_jpg.encode(_bmd);
_uploadService=new NetConnection();
_uploadService.objectEncoding=ObjectEncoding.AMF3
_uploadService.connect("http://.../amfphp/gateway.php");
_uploadService.call("UploadService.receiveByteArray",new Responder(success, error), jpg_binary, currentImageFilename);

 }

```

Many thanks for you help
