view cr image on runtime

hello, i download this code and its working;

Code:

---

            Dim dt As New DataTable
            ' object of data row
            Dim drow As DataRow
            ' add the column in table to store the image of Byte array type
            dt.Columns.Add("Image", System.Type.GetType("System.Byte[]"))
            drow = dt.NewRow
            ' define the filestream object to read the image
            Dim fs As FileStream
            ' define te binary reader to read the bytes of image
            Dim br As BinaryReader
            ' check the existance of image
            If File.Exists(AppDomain.CurrentDomain.BaseDirectory & "10157.Jpg") Then
                ' open image in file stream
                fs = New FileStream(AppDomain.CurrentDomain.BaseDirectory & "10157.Jpg", FileMode.Open)
            Else ' if phot does not exist show the nophoto.jpg file
                fs = New FileStream(AppDomain.CurrentDomain.BaseDirectory & "NoPhoto.jpg", FileMode.Open)
            End If
            ' initialise the binary reader from file streamobject
            br = New BinaryReader(fs)
            ' define the byte array of filelength
            Dim imgbyte(fs.Length) As Byte
            ' read the bytes from the binary reader
            imgbyte = br.ReadBytes(Convert.ToInt32((fs.Length)))
            drow(0) = imgbyte      ' add the image in bytearray
            dt.Rows.Add(drow)      ' add row into the datatable
            br.Close()              ' close the binary reader
            fs.Close()              ' close the file stream

            Dim rptobj As New CrystalReport1    ' object of crystal report
            rptobj.SetDataSource(dt)            ' set the datasource of crystalreport object
            CrystalReportViewer1.ReportSource = rptobj  'set the report source

---

the code creates new table..

My problem is, i have existing table that should display in the crystal report?

and also is it possible to create a new field in my existing table? (im using ms access as usual)

hope u could help me with this..
