The resolution of the 16 000 images I now have from 2010 are 3888×2592 pixels. So I selected 3888 images snapped during the day. Then I got some generous help from my blog readers and twitter followers. To make a script that would take one line from the first image, the next line from the next image and so on. Jo Christian Oterhals, Nikolai Kristiansen and Aslak Hellesøy provided complete code for the solution.
