A good photo goes a long way in explaining something – especially something complex like cities and transport. I’ve always tried to use decent photos of my own on this blog but I also have a lot of photos I’ve never really used and just left hanging around. Almost every photo I take I license under creative commons, in a license that means it is fine to use it for non-commercial purposes without a further explicit request to license it. I should remind you explicitly, if you are intending to use my photos in a journalistic context, to make a strong political point or to do anything where you are gaining income via advertising or charging you must ask first.
That over, where are the photos? Well, I keep them on flickr in the following galleries (updated as and when).
