Depends on the type of the Image.Source, assuming that you have a BitmapSource as in the article it should be along those lines:

var encoder = new PngBitmapEncoder();
encoder.Frames.Add(BitmapFrame.Create((BitmapSource)image.Source));
using (FileStream stream = new FileStream(filePath, FileMode.Create))
    encoder.Save(stream);

If it's a System.Drawing.Image object then just call Save?
