The Watermark Plugin settings are all active. I cannot see the watermark itself but I think this is how it is supposed to work. The images have to be watermarked. So: when all the information is in place in the website, then I will go through the images and watermark them. They have to be manually watermarked.
How to watermark an image.
Upload the image into the media library. Open the image module and upload the image from the media library. Make sure you click on Apply Watermark and wait for the check mark to appear. This tells you the watermark is in effect for this image.
