title: phpThumb cache problems
body: <p>I'm using phpThumb - the PHP thumbnail generator.</p>
  
  <p>'phpThumb.config.php':</p>
  
  <pre><code>$PHPTHUMB_CONFIG['cache_maxage'] = 10; 
  
  $PHPTHUMB_CONFIG['cache_maxsize'] = 1000; 
  
  $PHPTHUMB_CONFIG['cache_maxfiles'] = 10;   
  </code></pre>
  
  <p>but it does nothing... I've got 108 MB in 922 files... and it keeps growing.</p>
