Digipix, the watermark can be easily destroyed by even simple manipulations/modifications. Not worth the $ to pay for a easy to get around product.Originally posted by Digipix
As long as the protected image travels the web, it can be tracked. Like I said, what you are protecting are your own assets and this service is mostly used by those doing Stock Photography. It's true that it's a huge amount to spend on tracking, that's why when a culprit is caught and put to justice, he will have to pay a whole lot more to compensate the copyright owner's loss. This is just one of the solutions available and I'm not recommending it for that company. Just wanted to make a point that it's easy to commit a crime, but it's not easy to get away.
If the image is saved at too low a jpeg level, and the encoding is not strong even, there is a good chance that the watermark is lost too.
