Destructive Watermarks – Original photos are watermarked permanently!

The program does what it says. Allows you to put a watermark on your photos. It gives you decent options on size and position. However it doesn’t tell you that it’s permanent and there is no undo. Once your photo is watermarked, it’s done- there’s no turning back unless you have an original to return it back to normal.

Unfortunately, I need a non-destructive solution. You probably do as well.
