CIMY Header Image Rotator

Hi

I’d like to use this plug in instead of the themes (F8 lite) header and slideshow feature, but there’s so many option/code in the existing code that I’m not sure what to change and how to get it running, can someone point me in the right direction please?

The plugin says to post their code where you would like it to be seen, but when I replace <?php get_header(); ?> with their code nothing happens
