Set crystal report image at runtime in vb.net

Hi Experts,

I have the following code: -

Imports System.Windows
Imports CrystalDecisions.CrystalReports.Engine
Public Class Form1
    Dim rpt As New CrystalReport1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim x As Integer
        Dim imageData() As Byte

        Dim ds As New InvoiceDataSet
        Dim imagepath As String = "c:\test.gif"
        Dim fi As New System.IO.FileInfo(imagepath)
        Dim imgstream As System.IO.Stream = fi.OpenRead
        x = CType(imgstream.Length, Integer)
        ReDim Preserve imageData(x)
        x = CType(fi.Length, Integer)
        imgstream.Read(imageData, 0, x)
        ds.DataTable1.AddDataTable1Row(imageData)

        rpt.Load(Forms.Application.StartupPath & "\crystalreport1.rpt")
        rpt.SetDataSource(InvoiceDataSet1.Tables(0))
        CrystalReportViewer1.ReportSource = rpt
    End Sub
End Class

What I am trying to do is place an image onto a crystal report using vb.net 2005 with the in built crystal report function. My problem is that when I place the array into the dataset the datagrid viewer that I have set to view what’s in the dataset it always shows a red x almost like internet explorer when the image can not be found. I have set the dataset field to byte(). What am I doing wrong please?

Many Thanks
Lee
