class.upload.php is a powerful and mature PHP class to manage uploaded files, and manipulate images in many ways. The script is available under a GPL license.
class.php.upload seems to do everything I need, but I'd like to get the image from a different server by providing a URL instead of uploading from my local PC or reading a local file already on the PHP server. I've seen this called "transloading" on another site. Can this feature be added to this package?
Thanks.
