i get certain graphs on calculation and i need to display the images of graph in the crystal report in the report section. how to do that.
the following code i have written :

/// <summary>
      /// To load the Image stored in the given filepath
      /// </summary>
      /// <param name="filePath"></param>
       private void LoadImage(string filePath)
       {
           //1) create an instance of type dataTable and store the images in it.
           DataTable imageTable = resultDataSet.Tables["GraphsImages"];
           // 2) insert the desired number of rows in the table that holds the images.
           DataRow newRow = imageTable.NewRow();
           // 3) get the image file into a stream reader.
           FileStream fs = new FileStream(filePath, System.IO.FileMode.Open, System.IO.FileAccess.Read);
           byte[] Image = new byte[fs.Length];
           fs.Read(Image, 0, Convert.ToInt32(fs.Length));
           fs.Close();

           newRow[0] = filePath;
           newRow[1] = Image;
           imageTable.Rows.Add(imageTable);

       }

and in the other method i call the loadimage function:

/// <summary>
        /// Handles the Click event of the btnGenerateReport control.
        /// </summary>
        /// <param name="sender">The source of the event.</param>
        /// <param name="e">The <see cref="RoutedEventArgs" /> instance containing the event data.</param>
        private void btnGenerateReport_Click(object sender, RoutedEventArgs e)
        {
            string filePath = @"c:\temp\interaction.bmp";
            InteractionChart.SaveBitmap(filePath);
            //VolumeChart.SaveBitmap(@"c:\temp\volumechart.bmp");
            //NetTorqueChart.SaveBitmap(@"c:\temp\netTorqueChart.bmp");
            //NetWOBChart.SaveBitmap(@"c:\temp\netWOBChart.bmp");
            //AreaChart.SaveBitmap(@"c:\temp\areaChart.bmp");
            //DPCChart.SaveBitmap(@"c:\temp\DPCChart.bmp");
            //ForceChart.SaveBitmap(@"c:\temp\forcechart.bmp");
            //WearRateChart.SaveBitmap(@"c:\temp\wearRateChart.bmp");
            LoadImage(filePath);
            ReportGenerated(this);
        }

but i am not getting the image. how will i get it? very urgent.
