Gallery template not refreshing

Hi,

I have a special gallery template 'case-study.html' that is for albums in a certain category.

In case-study.php I use the page function:

<?php perch_gallery_album_images(perch_get('s'),           
                array('template' => 'case-study.html')); ?>

I have modified case-study.html to show a large image, however it is not updating the view on page reload. I have resubmitted all pages and done another Save on the album in the Gallery app. Any tips to force the re-load of this template?

Thanks
