I would like to include image in a jupyter notebook.
If I did the following, it works :
from IPython.display import Image
Image(\"img/picture.png\")

The image is actually embedded in the ipynb Notebook and you don't need to mess around with separate files. This is unfortunately not working with Jupyter-Lab (v 1.1.4) yet.
Edit: Works in JupyterLab Version 1.2.6
