Well, that's just how I would do it. If the other way works, and it's less work for you, then there's no need to change it. It's just natural for me to use RequestHandler since on most sites I already have it loaded for AJAX and RSS.
As to manipulating images with PHP... I've only minimal experience with that. I guess it depends on which graphics library you're using. You could try GD's imagecreatefromstring() ( http://us2.php.net/manual/en/function.imagecreatefromstring.php ).
