I have a directory of jpegs that I want to display thumbnails of and have a
link to the original jpeg. I would rather not create separate thumbnails
images preferring to create them in memory to display them. I have installed
GD v.1.8.4. The code below outputs jumbled text to the browser (possibly the
jpeg stream?). Code is as follows:

        <td><img alt="text" src="<?php echo CreateThumbnail(); ?>"
valign="top" /></td>

function CreateThumbnail()
      $x = 130;
      $y = 100;

      $quality = 75;

      $thumbnail = imagecreate($x, $y);
      $originalimage = imagecreatefromjpeg('test.jpg');

      imagecopyresized($thumbnail, $originalimage, 0, 0, 0, 0, $x, $y,

      header("Content-Type: image/jpeg");
