s = 0;
string PhotoIns;
FileStream fs = new FileStream("d:\\123.JPG", FileMode.Open, FileAccess.Read);
byte[] im = new byte[fs.Length];
fs.Read(im, 0, im.Length);
photo.id = getId();
photo.Image = im;
PhotoIns = "insert into person_picture(persp_id,persp_comment,persp_picture) values('"+@photo.id+"','"+@photo.Comment+"','"+@photo.Image+"')";

OracleConnection oracon = new OracleConnection(con);
oracon.Open();
OracleCommand InsPhoto = new OracleCommand(PhotoIns, oracon);
OracleParameter par = new OracleParameter();
par.Direction = ParameterDirection.Input;
InsPhoto.Parameters.Add("@photo.id", OracleType.Number).Value = photo.id;
