28.3. Inserting Figures

While properly documenting the code itself is the first step to take, you may want to include figures that explain overall concepts of a package, module, or class (see Fig. 5.1). To do this, first simply place the image file you would like to display into your <package>/doc> directory. You can then place the image (in this case cat.jpg) into the documentation by using

.. _cat_picture:

.. figure:: cat.jpg
  :width: 40em
  :align: center

  Why is it always cats?

where we have also included the reference cat_picture to use later. This markup would display the image as

Fig. 28.1 Why is it always cats?

Just as with other components, we can reference the picture from the text by using :ref:`cat_picture`. Which then appears as a reference using the caption text as Why is it always cats?. As before, we could use the :numref: syntax to get a numbered reference displayed as Fig. 28.1.
