Fichero php para generar imagenes - para usar en modo cron

[gusman126]

Hola a todos, ultimamente estoy migrando algunas tiendas y uno de los problemas que me encuentro es la generación de miniaturas , tarda una eternidad y bloquea el sistema, por lo que he encontrado un fichero php que genera las miniaturas y por lo tanto se puede añadir a un cron

EL fichero original :

https://github.com/dvershinin/prestashop-cli/blob/master/regenerate-thumbnails.php

El fichero cambiado para que funcione desde un fichero en la raiz de la tienda

<?php

/*
 * Its simple class for resizing (all) (products) images in Prestashop
 * There is often a problem with resizing through dummy "Resize button" - PHP has timeout,
 * if not then gateway timeoout ...
 * So here it is, use it with PHP-CLI ( max_exec_time must be set to unlimited ... )
 */

// TODO Only products images
// TODO Regenerating all product images

// !!!! YOU MUST EDIT THIS
$PS_HOME        = dirname(__FILE__);    // directory wheres your PrestaShop installed
require_once dirname(__FILE__) ."/config/settings.inc.php";
$PS_IMG_PATH    = dirname(__FILE__) ."/img/p/";  // directory wheres your images

// DO NOT EDIT THIS BABY, UNLESS YOU KNOW WHAT ARE YOU DOING
require_once dirname(__FILE__) . "/config/config.inc.php";

Editado. tenia un problema y era que siempre generaba los ficheros, no comprobaba si existía o no , solucionado

$thumb = substr($imgPath, 0, strrpos( $imgPath, '.' ) ).'-'.stripslashes($imageType[ 'name' ] ). '.jpg';
                    if(file_exists($thumb)){
                        continue;
                    }
