## Remote sites

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

1. edit file tools/create_listing_file_local.inc.php, by modifying parameters section such as `$conf['prefix_thumbnail']` or `$conf['use_exif']`.
2. using ftp, place the files tools/create_listing_file.php and tools/create_listing_file_local.inc.php (modified) on your distant website, in the same directory as your album directories (as the directory galleries of this website). For example, let's say that you can access http://example.com/galleries/create_listing_file.php.
3. go to administration panel » Tools » 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 information
   3. clean : removes distant listing.xml file
   4. delete : deletes the site (and all related albums and photos) in the database
