You probably shouldn't draw directly on the PictureBox. You need to use a Bitmap instead. Try putting the bitmap in the PictureBox.Image and then call Save(). http://bytes.com/topic/c-sharp/answers/266074-how-save-picturebox-image-into-jpg-file http://dotnet-munesh.blogspot.in/2014/05/how-to-save-image-in-database-in-window.html private void button1_Click(object sender EventArgs e) { pictureBox1.ImageLocation=@C:\Documents and Settings	r1g3800\Desktop\WALKING\30P\100000.jpg ; } private void button2_Click(object sender EventArgs e) { pictureBox1.Image.Save(@C:\Documents and Settings	r1g3800\Desktop\WALKING\30P\100000test.jpgImageFormat.Jpeg); } private void pictureBox1_Paint(object sender PaintEventArgs e) { } private void button3_Click(object sender EventArgs e) { Bitmap bmp = new Bitmap(pictureBox1.Image); Graphics gr = Graphics.FromImage(bmp); Pen p = new Pen(Color.Red); p.Width = 5.0f; gr.DrawRectangle(p 1 2 30 40); pictureBox1.Image = bmp; }
