[antopix]

<?php

include "SmartImage.class.php";

$directory = "foto";

if (is_dir($directory)) { 
      if ($directory_handle = opendir($directory)) { 
         while (($file = readdir($directory_handle)) !== false) { 
             
            if((!is_dir($file))&($file!=".")&($file!="..")) 
                $img = new SmartImage($file); 
                $img->resize(400, 220, true);  
                $img->saveImage("newimages/$file", 85); 

        }//fine while 
        closedir($directory_handle); 
    } 
} 
else echo "non è una directory";
$img->close();

?>

Probabilmente sbaglio, ma...non mi funziona
