Methods to Add Images in Jupyter Notebook
There are multiple ways to add images in Jupyter Notebook. Depending on your needs, you can choose the method that best suits your project. Here are the most common ways:
1. Using Markdown
Markdown is a simple and popular way to include images in Jupyter notebooks. It allows you to display an image directly in your notebook without using Python code.
Here's the breakdown of the syntax:
- ![Image Description]: This part is where you add a description or alt text for the image.
- (image_path_or_url): Here, you provide the path to the image, either locally or from the web.
2. Using Python Code (IPython.display)
You can also use Python code to display images with the help of the IPython.display library. This method is useful when you want to include images that are dynamically generated or need to be processed before being displayed.
from IPython.display import Image
Image(filename='image_path')This method offers flexibility, allowing you to display images stored locally or fetched from a URL. You can even modify images programmatically before displaying them.
3. Using Matplotlib
If you need to display images alongside other plots and data visualizations, Matplotlib provides an easy way to do this. Using the imshow() function, you can display images directly within a plot.
import matplotlib.pyplot as plt
import matplotlib.image as mpimg
img = mpimg.imread('image_path')
imgplot = plt.imshow(img)
plt.show()This method is particularly useful when you need to overlay images on plots or manipulate the images before showing them.
4. Displaying Web Images
If your image is hosted online, you can display it directly from its URL using either Markdown or the IPython display function. For example:
from IPython.display import Image
Image(url='image_url')This is a great way to quickly reference images without the need to download or store them locally.

Using Markdown to Display Images in Jupyter Notebook
One of the simplest and most effective ways to display images in Jupyter Notebook is by using Markdown. Markdown allows you to quickly integrate images without needing to write any Python code. This method is perfect for when you want to add an image to enhance the presentation of your data or provide extra context to your analysis. It’s easy to use and great for visual learners.
To display an image with Markdown, you use the following syntax:
Here's a quick breakdown of the components:
- ![Image Description]: This is the alt text or description that appears if the image fails to load. It's a good practice for accessibility.
- (image_path_or_url): This is where you place the path to the image. It can be either a relative path (for local images) or a URL (for online images).
For example:
This would display an image from a folder called "images" in your project directory. If you're working with online images, you could use a URL like this:
Markdown is a great way to include images because it's simple and integrates smoothly into your notebook without the need for additional setup or libraries.

Incorporating Images with Python Code in Jupyter Notebook
If you're looking for more control over how images are handled in your Jupyter Notebook, incorporating images with Python code is a powerful option. This method is ideal if you want to dynamically load images, process them before displaying, or work with images that are generated or modified by your code.
One of the easiest ways to include images in a Jupyter notebook using Python is through the IPython.display module. It allows you to display images stored locally or from a URL with just a few lines of code.
Here’s an example of how to use Python code to display an image:
from IPython.display import Image
Image(filename='path_to_your_image.jpg')If your image is hosted on the web, you can use the URL instead of a local path:
Image(url='https://example.com/image.jpg')For more flexibility, you can also use the Matplotlib library to display images as part of your data analysis process. This is particularly helpful when you need to add images to plots or charts. For example:
import matplotlib.pyplot as plt
import matplotlib.image as mpimg
img = mpimg.imread('image_path.jpg')
imgplot = plt.imshow(img)
plt.show()This approach gives you more control over the display of images, allowing you to adjust aspects such as size and positioning as part of your data visualization workflow.

Adjusting Image Size and Placement in Jupyter Notebook
Sometimes, simply adding an image isn’t enough. You may want to adjust the size or placement of an image to better fit your presentation or analysis needs. In Jupyter Notebook, there are a few methods you can use to control the dimensions and positioning of images, depending on whether you’re using Markdown or Python code.
Using Markdown to Adjust Image Size
In Markdown, you can adjust the size of an image by adding HTML-style attributes within the image tag. While Markdown itself doesn't offer direct support for resizing images, you can use the width and height attributes to specify the size:
In this example, the image will be resized to 400px in width and 300px in height. You can adjust these values based on your needs.
Using Python Code to Adjust Image Size
If you prefer working with Python code, the IPython.display.Image module also allows you to adjust the size of the image by passing the width and height parameters when calling the image:
from IPython.display import Image
Image(filename='path_to_image', width=400, height=300)This will resize the image to fit the specified dimensions within your notebook.
Adjusting Image Placement in Markdown
Markdown provides limited options for adjusting the placement of an image. However, you can use HTML tags within Markdown to align an image. For example, to center an image, you can wrap it in a <div> tag with a style attribute:
<div style="text-align: center;">
This centers the image within the page. You can also use other HTML tags to adjust the positioning, such as left or right alignment.
Adjusting Image Placement in Python Code
If you're working with Matplotlib or other Python libraries, you can control where the image appears by customizing the plot or figure layout. For example, you can use plt.subplots_adjust() to manage the positioning of images within a plot or layout:
import matplotlib.pyplot as plt
import matplotlib.image as mpimg
img = mpimg.imread('image_path')
fig, ax = plt.subplots()
ax.imshow(img)
plt.subplots_adjust(left=0.1, right=0.9, top=0.9, bottom=0.1) # Adjust image placement
plt.show()With these methods, you can control the placement and size of images to suit your needs, ensuring that your Jupyter Notebook is not only informative but also visually appealing.
