                        Uri uri = new Uri(userImage, UriKind.Absolute);
                        image2.Source = new BitmapImage(uri);

Answer 1

To convert above image to a bytearray you can try:

MemoryStream ms = new MemoryStream();
image2.Source.Save(ms,System.Drawing.Imaging.ImageFormat.Jpeg);
byte[] imageBytes = ms.ToArray();

EDIT:

If the above code doesn’t give the desired results you can try:

WriteableBitmap bmp = new WriteableBitmap((BitmapSource)image2.Source);
byte[] byteArray;

using (MemoryStream stream = new MemoryStream()) {

    bmp.SaveJpeg(stream, bmp.PixelWidth, bmp.PixelHeight, 0, 100);

    byteArray = stream.ToArray();
}

You need to include the Microsoft.Phone namespace for SaveJpeg to work.
