Thanks Preston, I will do that. One other thought, I've noticed after I edit an image (I use paint shop pro) that the original properties from the camera go away. Maybe I need to set something in PSP to save those or put in new ones? This is one reason I was asking about using the digital (invisible) watermark, which I think would be permanently built into the image, even if it is edited and/or the signature cropped off. Although maybe I'm not understanding how that type of watermark works.
