[freude]

hallo zusammen,

kann mir jemand erklären was ich falsch mache?

#test.php
<?php
   $verz = dir("C:/MonWeb/Grafiken/Bilder/");
   while ($datei = $verz->read())
   {
    if (eregi(".jpg$", $datei))
    {
     echo("<a href='".$datei."'>");
     echo("<img src='thumb.php?image=".$datei."'>");
     echo("</a>\n");
    }
   }
  ?>
#test.php

<?php

#thumb.php
header("Content-type: image/jpeg");
$scale = 2;

$size = getimagesize($_GET[image]);
$width = round($size[0]/$scale);
$height = round($size[1]/$scale);
$src = imagecreatefromjpeg($_GET[image]);
$dest = imagecreate($width,$height);
imagecopyresized($dest,$src,0,0,0,0,$width,$height,$size[0],$size[1]);
imagejpeg($dest);
imagedestroy($dest);
imagedestroy($src);
?>
#thumb.php
