you can using c# code

 filestream fs = new filestream(@"c:\myimage.jpg", filemode.open, fileaccess.read);//or .jpg, etc...         image image = image.fromstream(fs);         fs.close();          bitmap b = new bitmap(image);         graphics graphics = graphics.fromimage(b);         var date = convert.tostring(datetime.now);         graphics.drawstring(date, this.font, brushes.black, image.width - (date.length*5), 0);          b.save(@"c:\myimage.jpg", image.rawformat);          image.dispose();         b.dispose();
