Does anyone know of any free invisible watermarking tools out there? Digimarc is too expensive for me…

Thanks Natty but I could just do that in Photoshop. I guess what I was looking for is something along the lines of a free plugin that could embed and invisible watermark in an image.
well photoshop can do that … go to filter, Digimark …is that what you mean ?
Isn’t there a hefty charge for that?
mmm …i dont know to be honest ?
