I can see how it might be counterproductive to do this live in the browser, as someone with an ounce of technical skills can find your un-watermarked images.

But using this to generate a watermark and upload it to somewhere like S3, to then display on pages is pretty sweet.

For instance, this might be utilized by a CMS plugin to support uploading images, watermarking them, and shipping them off to the cloud.

Simpsons did it.
