The Micro.Blog Anatole theme claims thumbnails in its list of features, however there’s no setting to turn that on. I asked in the MB Help forum and @sod helped me make it work — Anatole theme question: how to display Post Thumbnails?

The solution involved replacing a small portion of layouts/index.html and worked perfectly.

My website now includes images on the Home Page above the post extracts.
