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.
You cannot have diagonal text using <>image_text (although it is planned for a future version). However, you can very simply create a transparent image with your text in diagonal, and apply it as a watermark.
