I have changed the way, the photos are sorted.
Now they are not longer sorted by their "id", but by their "date of creation", that means, the time when they were inserted into the database.
So when I now add "old" photos, from an older version of this site, I want to give them their old "creation date".. (that will take some time, because it will be done manually for each photo)
This way, I hope only "really new" photos will then appear on the start page, and older ones will be inserted on higher page numbers. The archives page should now also grow and show older years. The oldest one should be 2010. I guess in that year I started using a database.
The website itself started in 2009, I believe...
