Well, maybe not the most useful task, but important to fetch and review something in the past. All
galleries between 2002 and 2016 on the web pages should be working now. Maybe just the one or the other link to be controlled, but all pictures online, after some years where some tools were not perfectly working. Now those tools are removed.
What is left to do? Review the links, review the libraries and complete the years between 2017 and 2019.
