I think I found one of the problems - the defined cache directory in image.php should be the path from the root, not the complete path starting with /home7/winesof/....
The other interesting thing is that if I call http://www.winesoffranceinc.com/testing/portfolio/labels/image.php there is an error. I even tried removing all of the code and replacing it with a simple html header and it doesn't work. Any ideas?
part of image.php code:
if (!isset($_GET['image']))
{
header('HTTP/1.1 400 Bad Request');
echo 'Error: no image was specified';
exit();
}

define('CURRENT_DIR', dirname(__FILE__));
define('CACHE_DIR_NAME', '/testing/portfolio/labels/thumbs/');
define('CACHE_DIR', CURRENT_DIR . CACHE_DIR_NAME);
define('DOCUMENT_ROOT', $_SERVER['DOCUMENT_ROOT']);
// Images must be local files, so for convenience we strip the domain if it's there
$image = preg_replace('/^(s?f|ht)tps?:\/\/[^\/]+/i', '', (string) $_GET['image']);
// For security, directories cannot contain ':', images cannot contain '..' or '<', and
// images must start with '/'
if ($image{0} != '/' || strpos(dirname($image), ':') || preg_match('/(\.\.|<|>)/', $image))
{
header('HTTP/1.1 400 Bad Request');
echo 'Error: malformed image path. Image paths must begin with \'/\'';
exit();
}
// If the image doesn't exist, or we haven't been told what it is, there's nothing
// that we can do
if (!$image)
{
header('HTTP/1.1 400 Bad Request');
echo 'Error: no image was specified';
exit();
}
// Strip the possible trailing slash off the document root
$docRoot = preg_replace('/\/$/', '', DOCUMENT_ROOT);
if (!file_exists($docRoot . $image))
{
header('HTTP/1.1 404 Not Found');
echo 'Error: image does not exist: ' . $docRoot . $image;
exit();
}
// Get the size and MIME type of the requested image
$size = GetImageSize($docRoot . $image);
$mime = $size['mime'];
// Make sure that the requested file is actually an image
if (substr($mime, 0, 6) != 'image/')
{
header('HTTP/1.1 400 Bad Request');
echo 'Error: requested file is not an accepted type: ' . $docRoot . $image;
exit();
}
$width = $size[0];
$height = $size[1];
$maxWidth = (isset($_GET['width'])) ? (int) $_GET['width'] : 0;
$maxHeight = (isset($_GET['height'])) ? (int) $_GET['height'] : 0;

{

$lastModifiedString = gmdate('D, d M Y H:i:s', filemtime($docRoot . '/' . $image)) . ' GMT';
