Hi darrenherbold, if you're referring to the slider on filmcrewgigs.com I'm using the
WP layerslider plugin. The child theme Eva has a built in slider but it only allows for one large image and we needed more flexibility.
WP layerslider can do just about anything: video, text, animation, images, transitions. You can get it on Code Canyon. Once the plugin is installed I just had to add this code to bottom of header.php just above final div tag:
<?php if (is_front_page()) echo do_shortcode('[layerslider id="2"]'); ?>
Hope that helps,
Tim
