ipython notebook read multiple images and display in CELL

Question

How do I do the above ? This is my code but it doesn't work nothing is displayed

from PIL import Image
import glob
image_list = []
for filename in glob.glob('<my directory>.pgm'):
    im=Image.open(filename)
    image_list.append(im)

import matplotlib.pyplot as plt

for i in range(10):
    plt.figure()
    plt.imshow(image_list[i])

I would like it to be displayed in the cell

Can you add plt.show() after plt.imshow(image_list[]) inside the loop ? — mkarts, Jun 27 '16 at 13:40
Hi thanks. I have but the images are not displayed in a cell i.e. new windows is created for the images. — Kong, Jun 27 '16 at 13:41
you should add : "%matplotlib inline" before your code above — mkarts, Jun 27 '16 at 13:43

If you're interested in a much simpler and faster way of displaying images I recommend IPyPlot package:

import ipyplot

ipyplot.plot_images(images_list, max_images=20, img_width=150)

It's capable of displaying hundreds of images in a grid-like format within just 60-70ms

You would get a plot similar to this:

there's a param called `show_url` which you can set to `False` like this: `ipyplot.plot_images(images_list, max_images=20, img_width=150, show_url=False)` – Karol Żak Oct 21 '21 at 15:58

In your case, you should add %matplotlib inlinebefore your code and make sure that after plt.imshow(images_list) you add plt.show() as well so matplotlib renders your images.
