Answer 1

If you have a WriteableBitmap, for example called LoadedPhoto, you can try:

using (MemoryStream ms = new MemoryStream()
{
    LoadedPhoto.SaveJpeg(ms, LoadedPhoto.PixelWidth, LoadedPhoto.PixelHeight, 0, 95);
    ms.Seek(0, 0);
    byte[] data = new byte[ms.Length];
    ms.Read(data, 0, data.Length);
    ms.Close();
}

If you’re using WriteableBitmapEx library from CodePlex, it can do a conversion to byte array, too
