        {
            Point myPoint = new Point(e.X,e.Y);
            PictureBox pic = new PictureBox();
            pic.BackColor = Color.Transparent;
            pic.Location = myPoint;
            pic.SizeMode = PictureBoxSizeMode.StretchImage;
            switch(flag)
            {
                case 0:
                    pic.Size=new Size(18,18);
                    pic.Image = Properties.Resources._1;
                    break;
                case 1:
                    pic.Size = new Size(24, 24);
                    pic.Image = Properties.Resources._3;
                    break;
                case 3:
                    pic.Size = new Size(30, 30);
                    pic.Image = Properties.Resources._5;
                    break;
            }
            if (e.Button == MouseButtons.Right)
            {
                pictureBox1.Controls.Add(pic);
            }
        }
