                button2.BackgroundImage = Image.FromFile("C:\\Users\\rati\\Desktop\\ks.png");
            }

        }

        private void button3_Click(object sender, EventArgs e)
        {
            button2.BackgroundImageLayout = ImageLayout.Stretch;
            button2.BackgroundImage = Image.FromFile("C:\\Users\\rati\\Desktop\\ks.png");

Just made a button by using the designer with the following code:

this.button1.BackColor = System.Drawing.Color.DodgerBlue;
this.button1.BackgroundImage = global::WindowsFormsApplication.Properties.Resources.ChargeImage;
this.button1.BackgroundImageLayout = System.Windows.Forms.ImageLayout.Zoom;
this.button1.Image = global::WindowsFormsApplication.Properties.Resources.DatabaseImage;
this.button1.Location = new System.Drawing.Point(12, 12);
this.button1.Name = "button1";
this.button1.Size = new System.Drawing.Size(264, 160);
this.button1.TabIndex = 0;
this.button1.UseVisualStyleBackColor = false;

And that is the result:

So what is your problem?

You can edit your pictures with a method like this:

private static void DrawLinesOnBitmap(Bitmap bmp)
{
   using (var p = new Pen(Color.Black, 5))
   {
      using (var g = Graphics.FromImage(bmp))
      {
         g.DrawLine(p, 0, 0, bmp.Width, bmp.Height);
      }
   }
}

This method adds a line from the left top corner to the right bottom corner. Just draw some more lines and you should get your wanted result.
