#4 Write the code for loading the image to our image control

```var openFrame = new Microsoft.Win32.OpenFileDialog { Filter = "JPEG Image(*.jpg)|*.jpg" };

#5 Write the code for detecting the faces count

#6 Write the code for drawing the rectangles in faces

```if (facesFound.Length <= 0) return;

            {
                drwContext.DrawRectangle(Brushes.Transparent, new Pen(Brushes.Blue, 6),
                    new Rect(faceRect.Left * resizeFactor, faceRect.Top * resizeFactor, faceRect.Width * resizeFactor,
