Hi
Does anyone know how to do make it generate a thumbnail that could go under the subfolder "thumbnail"?
Here are my workings with: http://nz.php.net/manual/en/function.imagecopyresampled.php implementation attempt. I think the header content-type is a problem because it thendisplays the URL of the page and not the content on the page.

$data .= $file[$i];
