I have enabled watermarking and enabled all usergroups for:
These checked usergroups will have their products stamped with your overlay product.
However, still some images do not have watermarks. Even images in the same category some show and some don't show watermarks.
shows the first image with a watermark yet others in the product review don't.
I use ImageMagick with a gif file image as the watermark. Have also Scan Database -> Check here to watermark unwatermarked files.
Furthermore, I thought watermarking manually changes the underlying image. So what is the use of having only certain usergroups product stamped? Does this only relate to these usergroups uploading and having their images watermarked, or does it mean members in this group will see the watermark?
Any light on this would be much appreciated. Thank you.
