After reading other's posts related to watermarking... there seem to be no solution, but watermarking your pics yourself with a photo/design program. I use ACDsee do you have other suggestions that might be faster??). Using a photo program will give you more flexibilty, but it would be great if a watermark module would really work as we wanted, that would save me lots of time..
I browsed the Prestashop add-on and there is only one paying watermarking module, which is really surprising.
Thank you for all your help.
it is being great to read and supported by you guys.
