So, you can easily choose the folders instead of typing a comma separated list. * My hack involves 3 files : - /wp-content/plugins/nextcellent-gallery-nextgen-legacy/admin/ajax.php –> adding of checkbox (and some dirty inline CSS to align checkbox) - /wp-content/plugins/nextcellent-gallery-nextgen-legacy/admin/addgallery.php– > managing of the array of checkbox (and some typos) - /wp-content/plugins/nextcellent-gallery-nextgen-legacy/admin/functions.php– > adding of function import_galleries($folders_list) which is mainly a copy of import_gallery($galleryfolder) with a “foreach” and hack for the thumbnails creation * The first hack in [the old post](http://wordpress.org/support/topic/plugin-nextgen-gallery-mass-batch-import-or-upload?replies=15) had a bug : the thumbnails are created for only one gallery of the list. * My hack works better : I’ve imported almost 100 galleries and created +3250 thumbnails in only one shot. The thumbnails creation is currently running and will take 4 hours 🙂 * In NextCellent, the thumbnails are created via Ajax : there is no timeout problem. The max execution time of PHP could be perhaps problematic for the creation of galleries in database, so I recommand to import folders by chunks of 10 or 20. * Here are the diffs for NextCellent **1.9.16** : * ``` --- ajax_original.php +++ ajax.php @@ -270,7 +270,7 @@ continue; if ( file_exists($root . $dir . $file) && $file != '.' && $file != '..' && is_dir($root . $dir . $file) ) { - echo "
