Hi Alish
Actually, there is not an option for that. But if you add a TOpenImageEnDialog to your form, you should be able to use:
https://www.imageen.com/help/TOpenImageEnDialog.OnCreateCustomControls.html
procedure TForm1.OpenImageEnDialogCreateCustomControls(Sender: TObject);
begin
(sender as TOpenImageEnDialog).PreviewCheckBox.Checked := False;
end;
