title: Save an image Resized with PHP
body: <p>I am working on improving my Facebook app. I need to be able to resize an image, then save it to a directory on the server. This is the code I have to resize:</p>
  
  <pre><code>&lt;?php
  // The file
  $filename = 'test.jpg';
  $percent = 0.5;
  
  // Content type
  header('Content-type: image/jpeg');
  
  // Get new dimensions
  list($width, $height) = getimagesize($filename);
  $new_width = $width * $percent;
  $new_height = $height * $percent;
  
  // Resample
  $image_p = imagecreatetruecolor($new_width, $new_height);
  $image = imagecreatefromjpeg($filename);
  imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);
  
  // Output
  imagejpeg($image_p, null, 100);
  ?&gt;
  </code></pre>
  
  <p>My question is, how would I save this resized image? Would I need to? Is there a way to <strong>manipulate the resized image without saving it</strong>?</p>
