    First i would like to suggest that, see below.

    Set the sourceStream of the Image for BitMap
        bitImage.StreamSource = new FileStream(fileName, FileMode.Open, FileAccess.Read);
    

    Then freeze the BitMap Image, or it ll not be in the instance as render able image.

    bitImage.StreamSource.Seek(0, System.IO.SeekOrigin.Begin);
    bitImage.Freeze();
    

    This should work, if not i personally think it is a bad idea to directly work with BitMaps, i use Bitmap to create image form file then copy it to the type Image(system.drawing iguess), something like below

    var tempImage = new Image {Source = bitImage};
    var imageObject = new ImageObject(tempImage, fileName);
    bitImage.StreamSource.Dispose();
    

    this tempImage can be added to ur page as regular UIElement. Hope it helps.
