Hi CapG57, thanks for the edit :)

Just keep in mind that there's a syntax for commons image, in this case it should be "wikimedia_commons = File:Information boards at the entrance to Llangennech railway station - geograph.org.uk - 4630409.jpg" instead of "wikimedia_commons = https://commons.wikimedia.org/wiki/File:Information_boards_at_the_entrance_to_Llangennech_railway_station_-_geograph.org.uk_-_4630409.jpg"
