I have the following code which is used as an example for a caching class from the following page
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Image Cache Test</title>
<link href='http://fonts.googleapis.com/css?family=Open+Sans' rel='stylesheet' type='text/css'>
<style>
body {
font-family: 'Open Sans', Helvetica, Arial, sans-serif;
}
img {
max-width: 100%;
}
</style>
</head>
<body>
<?php
$imagecache = new ImageCache();
$imagecache->cached_image_directory = dirname(__FILE__) . '../';
$cached_src_one = $imagecache->cache( 'background.jpg' );
echo '<p>Original file size: ' . filesize($imagecache->image_src) . ' bytes</p>';
echo '<p>PHPImageCach-ified file size: ' . filesize($imagecache->cached_filename) . ' bytes</p>';
echo '<p>Total image size reduction: ' . (((filesize($imagecache->image_src) - filesize($imagecache->cached_filename)) / filesize($imagecache->image_src))*100) . '%</p>';
?>
<img src="<?php echo $cached_src_one; ?>" alt="">
<hr>
<?php
$imagecache->check_link_cached = false;
$cached_src_two = $imagecache->cache( 'background.jpg' );
echo '<p>Original file size: ' . filesize($imagecache->image_src) . ' bytes</p>';
echo '<p>PHPImageCach-ified file size: ' . filesize($imagecache->cached_filename) . ' bytes</p>';
echo '<p>Total image size reduction: ' . (((filesize($imagecache->image_src) - filesize($imagecache->cached_filename)) / filesize($imagecache->image_src))*100) . '%</p>';
?>
<img src="<?php echo $cached_src_two; ?>" alt="">
<hr>
<?php
$cached_src_two = $imagecache->cache( 'http://placehold.it/350x350' );
echo 'Original file size: ' . filesize($imagecache->image_src) . ' bytes<br>';
echo 'PHPImageCach-ified file size: ' . filesize($imagecache->cached_filename) . ' bytes<br>';
echo 'Total image size reduction: ' . (((filesize($imagecache->image_src) - filesize($imagecache->cached_filename)) / filesize($imagecache->image_src))*100) . '%';
?>
<p>Because the "compressed" file size is larger than the original, a local copy of the original file will be server instead.</p>
<img src="<?php echo $cached_src_two; ?>" alt="">

</html>
I am getting the mentioned error and not sure if it has to do something with the code. Everything is relative in terms of paths.
