// order_by : how to change the order of display for images in a category ?
//
// There are several fields that can order the display :
//
//  - date_available : the date of the adding to the gallery
//  - file : the name of the file
//  - id : element identifier
//  - date_creation : date of element creation
//
// Once you've chosen which field(s) to use for ordering, you must chose the
// ascending or descending order for each field.  examples :
//
// 1. $conf['order_by'] = " order by date_available desc, file asc";
//    will order pictures by date_available descending & by filename ascending
//
// 2. $conf['order_by'] = " order by file asc";
//    will only order pictures by file ascending without taking into account
//    the date_available
$conf['order_by'] = ' ORDER BY file ASC, id ASC';

// order_by_inside_category : inside a category, images can also be ordered
// by rank. A manually defined rank on each image for the category.
//
// In addition to fields of #images table, you can use the
// #image_category.rank column
//
// $conf['order_by_inside_category'] = ' ORDER BY rank';
// will sort images by the manually defined rank of images in this category.
$conf['order_by_inside_category'] = $conf['order_by'];
