You can use Image.Save method which receives stream. Try this piece of code: Image img = new Bitmap(10, 10); byte[] binaryImage = null; using (System.IO.MemoryStream memStream = new System.IO.MemoryStream()) { img.Save(memStream, ImageFormat.Jpeg); memStream.Flush(); binaryImage = new byte[memStream.Position]; memStream.Position = 0; memStream.Read(binaryImage, 0, binaryImage.Length); } I've just written it from scratch without testing, but I'm sure that you'll test it :) Zoran

Instead of Image img = new Bitmap(10, 10) just write: Image img = picturebox.Image; That's all... The rest of the code has nothing to do with the method in which image was obtained. Zoran
