Using AsyncFileUpload and stored procedure

I been over a lot of AsyncFileUpload that save to hard drive and save to DB, but with not a stored procedure.

I tried with the following code, but when I view the database, I get 0x89 and my varbinary(max) data field.

Thanks,

if (AsyncFileUpload1.HasFile && AsyncFileUpload1.PostedFile != null)
{
string filename = System.IO.Path.GetFileName(AsyncFileUpload1.FileName);
string contentType = AsyncFileUpload1.ContentType.ToString();
using (Stream fs=AsyncFileUpload1.PostedFile.InputStream)
{
using (BinaryReader br = new BinaryReader(fs))
{
byte[] bytes = br.ReadBytes((Int32)fs.Length);
using (SqlConnection conn1 = new SqlConnection(ConfigurationManager.ConnectionStrings["xxx"].ConnectionString))
{
SqlCommand sqlcmd = new SqlCommand("usp_CustomerClientSave", conn1);
sqlcmd.CommandType = CommandType.StoredProcedure;
sqlcmd.Parameters.Add(new SqlParameter("@ClientID", System.Data.SqlDbType.Int)).Value = Convert.ToInt32(Decrypt(Request.QueryString["id"].ToString()));
sqlcmd.Parameters.Add(new SqlParameter("@UpdatedByID", System.Data.SqlDbType.Int)).Value = Convert.ToInt32(Session["id"].ToString());
sqlcmd.Parameters.Add(new SqlParameter("@filename", System.Data.SqlDbType.VarChar,100)).Value = filename;
sqlcmd.Parameters.Add(new SqlParameter("@ContentType", System.Data.SqlDbType.VarChar, 25)).Value = contentType;
sqlcmd.Parameters.Add(new SqlParameter("@Data", System.Data.SqlDbType.VarBinary,8000)).Value = bytes;
try
{
conn1.Open();
sqlcmd.ExecuteNonQuery();
}
catch (Exception ex)
{
throw new System.Exception(ex.ToString());
}
finally
{
conn1.Close();
sqlcmd.Dispose();
}
}
}
}
}
