## Remote sites

Piwigo offers the possibility to use several servers to store the images which will compose your gallery. It can be useful if your gallery is installed on one limited space and that you have a big quantity of images to be shown.

1. edit file tools/create_listing_file.php, by modifying parameters section such as `$conf['prefix_thumbnail']` or `$conf['use_exif']`.
2. place file tools/create_listing_file.php modified on your distant website, in the same directory than your category directories (as the directory galleries of this website) by ftp. For the example, let's say that you can access http://example.com/galleries/create_listing_file.php.
3. go to administration panel, Categories, Site manager. Ask to create a new site, for example http://example.com/galleries.
4. a new remote site is registered. You can perform 4 actions :
   1. generate listing : launches a distant request to generate a distant file listing
   2. synchronize : reads the distant listing.xml file and synchronizes with database informations.
   3. clean : removes distant listing.xml file.
   4. delete : deletes the site (and all related categories and elements) in the database.
