Spara fil utan Savedialog i VB 2010?

Hur får jag filen sparad med hjälp av denna kod utan använda mig av SaveDialog?

Private Sub OpenImage_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OpenImage.Click
        If OpenFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then
            ImageLabel.Text = OpenFileDialog1.FileName
            RectangleImage.BackgroundImage = Image.FromFile(ImageLabel.Text)

            Dim Newsize As New Size(100, 100)
            ResizedImage = New Bitmap(RectangleImage.BackgroundImage, Newsize)
            RectangleImage.BackgroundImage = ResizedImage
            RectangleImage.BackgroundImageLayout = ImageLayout.Stretch

        End If

        SaveFileDialog1.AddExtension = True
        SaveFileDialog1.DefaultExt = Path.GetExtension(ImageLabel.Text)

        Try
            Select Case SaveFileDialog1.FilterIndex
                Case 1
                    RectangleImage.BackgroundImage.Save(SaveFileDialog1.FileName, System.Drawing.Imaging.ImageFormat.Jpeg)

                Case 2
                    RectangleImage.BackgroundImage.Save(SaveFileDialog1.FileName, System.Drawing.Imaging.ImageFormat.Gif)
            End Select
            ResizedImage.Dispose()
        Catch ex As Exception
            MsgBox("Bildformatet felaktig")
        End Try
    End Sub
