How to move an image separately?

Question

C++ / C#

There are 2 pictures in the picture box, how can I move them separately?

the code:

private void pictureBox3_Paint(object sender, PaintEventArgs e)
        {
            Image c = sender as Image;

            Mg = new Bitmap(Mg, new Size(20, 20));
           // e.Graphics.DrawImageUnscaled(Mg, cx, cy);
            e.Graphics.DrawImageUnscaled(c, 20, 20);
        }

Answer 1

The resulting picture in the pictureBox is an indivisible image. Therefore, use pictureBox only for display, and keep the original pictures in memory and move.
