Adding a Second Header.php file

I am currently trying to add a second header.php file to my blog.

I have a flash file in the header.php file that I want to show on the index but I want a static .jpg image to show on my Pages and Posts.

I have done this before but I cannot for the life of me remember how!

I have currently tried this: <?php get_header(header2.php); ?>
and this: <?php get_header(header2); ?>
and this: <?php get_header(‘header2’); ?>

Can anyone help me?
Thank you so much in advance
