I've an 'interesting" issue. Suddenly the black and white pictures on a "slideshow page" on my website are too large. The color pictures are still the same as when I installed them. The black and white were also okay. The link to my website is https://klaassikkema.com/album/portrait-slideshow/
. I guess it has to to with something "auto resize". Good to know, I did not change anything, or at least I think I did not change something.
