Get Backround Image

Instead of a picturebox, you can draw directly on the form

    public partial class Form1 : Form
    {
        Image img;
        Font myFont = new Font("Arial", 12);
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            img = Image.FromFile("test.png");
        }

        private void Form1_Paint(object sender, PaintEventArgs e)
        {
            e.Graphics.DrawImage(img, 200,200);
            e.Graphics.DrawString("This is Kunal", myFont, Brushes.White, 350, 260);
        }
    }
}
