 System.Drawing.Image oImg = System.Drawing.Image.FromFile(strFileName);
           string PicText = "http://fanyanjun.cnblogs.com";
            System.Drawing.Graphics g = System.Drawing.Graphics.FromImage(oImg);
            g.DrawImage(oImg, 0, 0, oImg.Width, oImg.Height);
            System.Drawing.Font font = new System.Drawing.Font("Verdana", 20);
            System.Drawing.Brush brush = new System.Drawing.SolidBrush(System.Drawing.Color.Green);
            g.DrawString(PicText , font, brush, 10, 10);
