Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Dim fdialog As New OpenFileDialog()
    fdialog.FileName = String.Empty
    fdialog.Multiselect = True

    If fdialog.ShowDialog = DialogResult.OK Then
        If fdialog.FileNames.Length = 2 Then
            PictureBox1.Image = System.Drawing.Image.FromFile(fdialog.FileNames(0))
            TextBox1.Text = fdialog.FileNames(0)
            PictureBox2.Image = System.Drawing.Image.FromFile(fdialog.FileNames(1))
            TextBox2.Text = fdialog.FileNames(1)
        ElseIf fdialog.FileNames.Length = 1 Then
            PictureBox1.Image = System.Drawing.Image.FromFile(fdialog.FileName)
            TextBox1.Text = fdialog.FileName
            PictureBox2.Image = Nothing
            TextBox2.Text = String.Empty
        End If
