Generate watermarked images with watermark.js jQuery plugin

I'm having a hard time not calling this project stupid, because it is one the most moot things I've ever seen. Are you seriously generating watermarks on the client? What's the purpose of the watermark, then?<p>Open Firebug (or, ostensibly, disable javascript) and bam, all your images are ripe to steal, watermark-free.<p>This took me all of two seconds:<p><a href="http://www.patrick-wied.at/static/watermarkjs/jq/img/test1.jpg" rel="nofollow">http://www.patrick-wied.at/static/watermarkjs/jq/img/test1.j...</a>

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)<p>Whats the use case for this if not to prevent users from getting at the original un-watermarked image?<p>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.

Is this the most pointless jquery plugin ever created?
