Seems like watermarks that can be removed by turning off javascript in your browser wouldn't be too useful. (Unless you ran it on the server side? node.js/jsdom DOES run jQuery) Whats the use case for this if not to prevent users from getting at the original un-watermarked image? EDIT: I just saw the QR-Code example. Overlaying images on other images might be pretty useful, I was just focusing on the 'watermark' aspect.
