Well you certainly made it difficult to download the image!
I had to look at the page source to figure out
http://www.dahl-stamnes.net/Foto/img.php?img=20583
The image downloaded is a JPEG! Of course the image will be a lower
quality, and contain aliasing artifacts. What does he want?
If anything it should be even lower quality for web use, with a link to
a larger higher quality, and high bandwidth one, in PNG (only for
specific people like the owner).
PS: I would use a tiled watermark, as a centered one may not stop people
grabbing and cropping a relevent part that is not in the center of the
image.
Actually I thought it came out pretty good. Ask the person for a
specific example of the low quality aspect.
Also in what format did you get the photo? and was it high quality?
Compare against his specific example of the problem.
Remember every time a JPG image is loaded and saved it degrades. If the
user has done this before passing to you the quality will suffer.
The best source is the exact image generated by the digital camera
without any changes (or even a load an save from a viewer, just plain
file copies)
