Creare Script che genera pagine in base al contenuto cartella

[J.C. Design]

Per eliminare i puntini ho scritto così:

<?php
$dir = 'http://www.makingart.org/images/banner/';

if ($handle = opendir('/web/htdocs/www.makingart.org/home/images/banner')) {

    echo "<table border=\"0\">";
    
   while (false !== ($file = readdir($handle))) {
   if (($file != "..") and ($file != ".")) { 
   echo "
   <tr>
   <td>
   <img src=\"$dir$file\" />
   </td>
   <td>
   <form name=\"select_all\">
   <textarea readonly=\"readonly\" style=\"width:700px;height:15px;\" readonly=\"readonly\" name=\"text_area\" onClick=\"javascript:this.form.text_area.focus();this.form.text_area.select();\">$dir$file</textarea>
   </form>
   </td>
   </tr>";
   }
   }
   echo "</table>";
   closedir($handle); 
}
?>

ma le immagini si vedono a tratti, ogni tanto si vedono e altre no
