Here is a portfolio of featured WordPress sites for which I have done work. Click the thumbnail image for a larger screenshot and a link to more information about the site itself.

Default Gallery Type Template

This is the default gallery type template, located in:
/home/withavoi/public_html/jamesgoodrich.com/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.
