You can edit the metadata of the notebook as shown in the screenshot below and include supplementary files, select an image for displaying it in the gallery or provide a code example.
Otherwise you can do whatever you want. You can also include ipython magic commands, e.g
which then will be (as well as all the warnings) removed in the rendered html file of your example.
By default, the sphinx-nbexamples looks for pictures you created with matplotlib and saved it in the notebook. If such a picture exists, it uses the last created picture as a thumbnail in the gallery. For this example, we modified the the
thumbnail_figure key of the notebook metadata to use our own picture (the one you see above).
