I was wondering : is it a client side JS transformation? Yes. Then how will the developer monetize it? Sending it to server for something, anything? No, rather watermarking the image client side. Or NOT doing it if you pay. It would be interesting to watch this project succeed. I want it to. That will mean there's good business case in similar projects. Six months later, an "I made $xx from this app" will be a more interesting post than the project itself. $xx can be any amount. Even if it's not that high.
