Default Gallery Type Template
This is the default gallery type template, located in:
/mnt/web209/a1/21/5120021/htdocs/eifelpanorama/wp-content/plugins/nextgen-gallery/products/photocrati_nextgen/modules/nextgen_gallery_display/templates/index.php.
If you're seeing this, it's because the gallery type you selected has not provided a template of it's own.
