// image to byte[]
Image photo = new Bitmap(selectPictureFile);
System.IO.MemoryStream ms = new System.IO.MemoryStream();
photo.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
byte[] imagedata = ms.GetBuffer();


// byte[] to image
System.IO.MemoryStream ms = New IO.MemoryStream(imagedata)
Bitmap b = new Bitmap(ms);
//img = Drawing.Image.FromStream(ms)
