hi friends,
saving image to sql server field with image type is ok,
now how could I load this image to a control such as image control in asp.net ( in runtime ! )
I use this code in WinForm and it works:

cmd.CommandText = "SELECT image FROM table1 where id='U07WL'";
cmd.CommandType = CommandType.Text;
SqlDataReader reader = cmd.ExecuteReader();
reader.Read();
byte[] barrImg = (byte[])reader["image"];
string strfn = Convert.ToString(DateTime.Now.ToFileTime());
FileStream fs = new FileStream(strfn, FileMode.CreateNew, FileAccess.Write);
fs.Write(barrImg, 0, barrImg.Length);
fs.Flush();
fs.Close();
panel1.BackgroundImage = Image.FromFile(strfn);

but in asp.net we don't have backgroundImage property, instead we have ImageUrl for example ! is there any way !?

excuse my bad explanation and bad english,
thanks in advande
