UX in Jupyter — User input essentials (Part 2)

In Part 2 of the Jupyter user input essentials series, I will go over displaying images, using buttons, and file selector/uploader. If you are just getting started with ipywidgets, check out part one here.

Displaying an image

Displaying images or diagrams in notebooks can be a great way to convay information. Typically, you would use other packages such as OpenCV or Matplotlib to display images, but if you didnt want to have dependencies on those packages, the ipywidgets packages allows you to directly display an image from a file:

file = open("original.jpg", "rb")
image = file.read()
widgets.Image(
    value=image,
    format='jpg',
    width=600,
    height=100,
)
