This was inspired by this forum thread on the Piwigo forums. Set up rewrite rules in nginx where "piwigo" is the path the gallery lies in:

{{< highlight nginx >}}

location @rewrite { rewrite ^/piwigo/picture((/|).*) /piwigo/picture.php$1 last; rewrite ^/piwigo/index((/|).*) /piwigo/index.php$1 last; # The following is needed for batch operations which use i.php rewrite ^/piwigo/i((/|).*) /piwigo/i.php$1 last; }

location /piwigo { index index.php; try_files $uri $uri/ @rewrite; }

location ~ ^(?<script_name>.+?.php)(?<path_info>/.*)?$ { try_files $script_name = 404; fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock; fastcgi_param PATH_INFO $path_info; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } {{< / highlight >}}

Lastly, add the relevant information to the Piwigo configuration (LocalFiles editor):

{{< highlight php >}} $conf['php_extension_in_urls'] = false; $conf['question_mark_in_urls'] = false; {{< / highlight >}}
