To resize an image in a Jupyter notebook's Markdown cell, use an HTML <img> tag inline. Specify the image dimensions with the width and height attributes. Here's an essential snippet you can start with:

<img src="image.png" width="250" height="150">

You just replace src with your image path and adjust width and height to your desired pixel size.

For those pesky local images, don't forget to donon your attachment before the image name:

<img src="attachment:image.png" width="250" height="150">

Having trouble with aspect ratio? Just specify the width:

<img src="image.png" width="250">

For more flexible resizing, you might appeal to the IPython.display Image module:

from IPython.display import Image
Image(filename="image.png", width=250, height=150)

Make sure to import Image from IPython.display before use and modify the parameters just the way you like them.

Markdown limitations, meet HTML evolution

For Maintaining Aspect Ratios, HTML caps can save your Markdown day:

<div style="width: 50%;">
    <img src="star.jpg" alt="Star Image" width="100%"/>
</div>

Here, our “div” tag wraps the image, making it responsive to the width of the container.

Deep Dive: Conquering image control

Markdown syntax may fall short in dictating image sizes with ![](img.png). But fear not, Jupyter's interface absorbs HTML, effectively dodging this limitation.

Is the src in your source?

Mistakes in the src attribute will put your image out of sight. Correct filename for local images and correct URL for online images are key.

No more distortion

To prevent squished or stretched images, declare the width or height only:

<img src="image.png" width="300">
<!-- or -->
<img src="image.png" height="200">

Beware of the versions

Differences in Jupyter versions might affect image insertion and formatting. Don't hesitate to tinker around or read up on Jupyter's detailed documents.

The Inside Story of IPython's Image Module

When using Image from IPython.display, remember that it's much more exciting than standard Markdown, with additional features like embedding images straight from URLs:

from IPython.display import Image
Image(url="http://example.com/image.png", width=250)

Practical Cases and Caveman Steps

Facepalm moments: Look for typos in your filename or URL.
The lone import: Did you forget to put from IPython.display import Image before calling it?

Is my context your context?

Presenting in Jupyter: The width attribute as a percentage guarantees responsive images.
Creating documentations: Use well-defined dimensions for uniformity across devices.
