All the pictures are:

• under Creative Commons license. These are mainly the older CC0 license, essentially Public Domain. You may use them yourself if you want to. A credit saying where they came from and / or a link would be nice but it is not a legal requirement.

External links. Some images are quite large, so they’ve been put into image galleries on other sites. These images are all my own work and I retain the copyright.

Fair use. I support the idea of Fair Use, even if copyright law where you are doesn’t. If you want to use small amounts of my stuff, that’s fine. If you want to use substantial portions, please ask first, especially if you’re doing it for commercial use.

Educational use. If you are a teacher you may use my work to produce classroom material for yourself or your colleagues, provided you’re not doing it commercially
