I am trying to figure out a way to make the slideshow a part of the header. I see web sites that seem to do this but I'm at a loss right now.
The closest I can come to making it work is to include this code:
<?php echo do_shortcode('[slideshow id=20 w=400 h=300]'); ?>
This will not work for the Nextgen gallery for some reason but will work for other short tags.
