quiero utilizar la aplicación de Slimbox, "EasyGallery" y al editar el tema del directorio de imágenes no consigo codificar correctamente.
surge el mensaje "ERROR: Searched folders don't contain any image! Please change the $root_dir."
podeis decirme en qué está mal el código de EasyGallery.php?
(evidentemente, sí hay imágenes en el directorio "images")
el código utilizado es,
<?php
