1.load bmp to the pictureBox ( i know)

2.write some text on the pictureBox with the graphic object (i guess its on

You won't really be able to override the OnPaint for the PictureBox control.
But what you can do is to draw the text you want on the image that you will
load to the PictureBox. Try something like:

// pbPhoto = PictureBox control

if (no_image == null) {
no_image = new Bitmap(pbPhoto.Width, pbPhoto.Height);

using (Graphics g = Graphics.FromImage(no_image)) {
using (Font font = new Font(Font.Name, 14f, FontStyle.Bold)) {
SizeF size = g.MeasureString("My Sample Text", font);
g.DrawString(
"My Sample Text",
font,
new SolidBrush(Color.DarkGray),
(pbPhoto.Width - size.Width) / 2,
(pbPhoto.Height - size.Height) / 2);
}
}
}

pbPhoto.Image = no_image;
3.SAVE THE **NEW** BMP TO FILE. (the main difficult )

The Image class has a function called Save()
