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.
Yes, ITPC and EXIF (and other similar metadata) is lost if you manipulate the image.
I might add support for these -at least to keep the data in the file, not to change it-, assuming that there are functions in PHP to do it, such as iptcembed(), iptcparse() or the EXIF functions.

Maybe next version ;)
