Read Large Binary Data From Sql Server 2005

Hi
I've followed a tutorial on how to write and read varbinary(max) data to and from a database. But when i try to read the data i get the error that the data would be truncated, but only when the varbinary(max)  is greater then 8kB. I've used a system stored procedure (sp_tableoption) to set the table that holds the data to store data outside rows. To select the data i'm using a stored procedure:
  
            SELECT imageData , MIMEType FROM Pictures WHERE (imageTitle = @imageTitle)
       
And then using an .aspx page to Response.Write the data:
Using conn As New sql.SqlConnection
            conn.ConnectionString = ConfigurationManager.ConnectionStrings("myConnectionString").ToString


            Dim getLogoCommand As New sql.SqlCommand
            getLogoCommand.CommandType = Data.CommandType.StoredProcedure
            getLogoCommand.CommandText = "GetPicture"
            getLogoCommand.Connection = conn

            Dim imageTitleParameter As New sql.SqlParameter("@imageTitle", Data.SqlDbType.NVarChar, 200)
            imageTitleParameter.Value = Request("imageTitle")
            imageTitleParameter.Direction = Data.ParameterDirection.Input

            getLogoCommand.Parameters.Add(imageTitleParameter)

            conn.Open()

            Using logoReader As sql.SqlDataReader = getLogoCommand.ExecuteReader
                logoReader.Read()
                If logoReader.HasRows = True Then
                    Response.Clear()
                    Response.ContentType = logoReader("MIMEtype").ToString()
                    Response.BinaryWrite(logoReader("imageData"))
                End If

            End Using

            conn.Close()

        End Using

 Can anyone please help me with this?!
