Replacing Depth Data with a Static image - C# / Kinect

Question

I need to replace the background pixels which are not players with an Image, I can successfully replace the user pixel with the ColorFrameImage, but as soon as i try to replace the rest of the depth bits with the image pixels . . I get a XamlParseError exception

Update: The ims.PixelHeight & ims.PixelWidth are causing the exception . .

I maybe doing the Bitmap image to pixel conversion wrong. .

Any work around?

Here is the code:

public partial class MainWindow : Window
{

    Byte[] pixels;

    Byte[] pix;

    Byte[] pixy;

    BitmapImage ims;

    public MainWindow()
    {
        InitializeComponent();


        ims = new BitmapImage();
        ims.BeginInit();
        ims.UriSource = new Uri(@"/autumn_scene.jpg", UriKind.RelativeOrAbsolute);

        //int height = ims.PixelHeight;
       // int width = ims.PixelWidth;
        //int nStride = (ims.PixelWidth * ims.Format.BitsPerPixel + 7) / 8;

      //  pixy = new byte[(ims.PixelHeight* 4+1)];

      //  MessageBox.Show("Pixel Height" + ims.PixelHeight);
        MessageBox.Show("I hate Exceptions");

        //System.Console.WriteLine("Pixel Height" + ims.PixelHeight);

   //     ims.CopyPixels(pixy, nStride, 0);

      //  ims.EndInit();

        }
