You can use Thread. Start your Thread before ShowDialog and run below-shown method within that thread. To close that thread you need to use Thread Form's Shown Event. So that you can close thread after form successfully shown to the user. It is mandatory to close your thread.

    private static LoadingForm loadForm;

    static private void ShowForm()
    {
        loadForm = new LoadingForm();
        Application.Run(loadForm);
    }

This loadForm object should have your loading image in the background-image property of form.

I am showing minimal code so that you can do rest of the task by yourself. It's good if you do something by yourself. Beware of how to handle cross-thread exception whenever using Thread.

Hope this makes help.
