Thanks for your reply. I am using ‘infinite-photography’ and was following the steps on this page: http://www.doc.acmethemes.com/infinite-photography/#ThemeInstallation
I’m not entirely sure why I need to install any dummy data at all but the instructions said that so I went along with it. If I don’t actually need dummy data, I guess that would be the easiest solution. If I do, I could take a look at the links you sent.
Thanks,
Martin
