Different header with woocommerce and meteor slider

Hello everyone,
I come to you desperate after looking for a solution for long hours yesterday and this morning.

I have a website for a restaurant that also sell a product they make.

I have a meteor slider header set for the main restaurant pages, and a different header (one image only) for the woocommerce shop pages.

I’ve tried many different codes, but this one looks the most appropriate yet it won’t work. I simply had no header displayed on the woocommerce pages.

<?php
if ( is_woocommerce() ) :
get_header_image();
else :
if ( function_exists( 'meteor_slideshow' ) ) { meteor_slideshow( "main", "" ); }
endif;
?>

Of course I have the header I want on woocommerce pages set in the Header section.

I’m not an expect at all on php, but yet I understand what this bit of code is meant to do and I don’t understand why it doesn’t work.

Here is the website (sorry it’s in french, the shop part is in Boutique)

EDIT: I forgot to say I’m using the theme called Responsive.
