I am starting to depend heavily on the IPython notebook app to develop and document algorithms. It is awesome; but there is something that seems like it should be possible, but I can't figure out how to do it:
I would like to insert a local image into my (local) IPython notebook markdown to aid in documenting an algorithm. I know enough to add something like <img src="image.png"> to the markdown, but that is about as far as my knowledge goes. I assume I could put the image in the directory represented by 127.0.0.1:8888 (or some subdirectory) to be able to access it, but I can't figure out where that directory is. (I'm working on a mac.) So, is it possible to do what I'm trying to do without too much trouble?
Most of the answers given so far go in the wrong direction, suggesting to load additional libraries and use the code instead of markup. In Ipython/Jupyter Notebooks it is very simple. Make sure the cell is indeed in markup and to display a image use:
Further advantage compared to the other methods proposed is that you can display all common file formats including jpg, png, and gif (animations).
Files inside the notebook dir are available under a "files/" url. So if it's in the base path, it would be <img src="files/image.png">, and subdirs etc. are also available: <img src="files/subdir/image.png">, etc.
Update: starting with IPython 2.0, the files/ prefix is no longer needed (cf. release notes). So now the solution <img src="image.png"> simply works as expected.
I am using ipython 2.0, so just two line.
from IPython.display import Image
Image(filename='output1.png')
Getting an image into Jupyter NB is a much simpler operation than most people have alluded to here.
Simply create an empty Markdown cell.
Then drag-and-drop the image file into the empty Markdown cell.
The Markdown code that will insert the image then appears.
For example, a string shown highlighted in gray below will appear in the Jupyter cell:
Then execute the Markdown cell by hitting Shift-Enter. The Jupyter server will then insert the image, and the image will then appear.
I am running Jupyter notebook server is: 5.7.4 with Python 3.7.0 on Windows 7.
This is so simple !!
UPDATE AS OF March 18, 2021:
This simple "Drag-and-Drop-from-Windows-File-System" method still works fine in JupyterLab. JupyterLab inserts the proper HTML code to embed the image directly and permanently into the notebook so the image is stored in the .ipynb file. I am running Jupyter Lab v2.2.7 on Windows 10 Python 3.7.9 still works in JupyterLab. I am running Jupyter Lab v2.2.7 using Python 3.7.9 on Windows 10.
This stopped working in Jupyter Classic Notebook v6.1.5 sometime last year. I reported an bug notice to the Jupyter Classic Notebook developers.
It works again in the latest version of Jupyter Classic Notebook. I just tried it in v6.4 on 7/15/2021. Thank you Jupyter NB Classic Developers !!
If you want to display the image in a Markdown cell then use:
<img src="files/image.png" width="800" height="400">
If you want to display the image in a Code cell then use:
from IPython.display import Image
Image(filename='output1.png',width=800, height=400)
[Obsolete]
IPython/Jupyter now has support for an extension modules that can insert images via copy and paste or drag & drop.
https://github.com/ipython-contrib/IPython-notebook-extensions
The drag & drop extension seems to work in most browsers
https://github.com/ipython-contrib/IPython-notebook-extensions/tree/master/nbextensions/usability/dragdrop
But copy and paste only works in Chrome.
I put the IPython notebook in the same folder with the image. I use Windows. The image name is "phuong huong xac dinh.PNG".
In Markdown:
<img src="phuong huong xac dinh.PNG">
Code:
from IPython.display import Image
Image(filename='phuong huong xac dinh.PNG')
First make sure you are in markdown edit model in the ipython notebook cell
This is an alternative way to the method proposed by others <img src="myimage.png">:
It also seems to work if the title is missing:
Note no quotations should be in the path. Not sure if this works for paths with white spaces though!
Change the default block from "Code" to "Markdown" before running this code:
If image file is in another folder, you can do the following:
Last version of jupyter notebook accepts copy/paste of image natively
For those looking where to place the image file on the Jupyter machine so that it could be shown from the local file system.
I put my mypic.png into
/root/Images/mypic.png
(that is the Images folder that shows up in the Jupyter online file browser)
In that case I need to put the following line into the Markdown cell to make my pic showing in the notepad:
minrk's answer is right.
However, I found that the images appeared broken in Print View (on my Windows machine running the Anaconda distribution of IPython version 0.13.2 in a Chrome browser)
The workaround for this was to use <img src="../files/image.png"> instead.
This made the image appear correctly in both Print View and the normal iPython editing view.
UPDATE: as of my upgrade to iPython v1.1.0 there is no more need for this workaround since the print view no longer exists. In fact, you must avoid this workaround since it prevents the nbconvert tool from finding the files.
I never could get "insert image" into a markdown cell to work. However, the drag and drop entered the png file saved in the same directory as my notebook. It brought this text into the cell
""
The shift + enter > image is now displayed in notebook.
FWIW
You can find your current working directory by 'pwd' command in jupyter notebook without quotes.

I'm using VS Code to write Jupyter notebook as I feel more comfortable with it. I found out that there is no option to edit meta data of the cells in order to hide only select code cells. I also came across some answers suggesting to use # #hidden_cell in the code cell but that doesn't work or am I doing it wrong? not much information was available for this.
I tried using the command
jupyter nbconvert my_notebook.ipynb --no-input --to pdf
and that works fine but it removes all the code. I wish to remove only specific code cells.
You can use .env to hide the code.
hidden_code = (code)
Then use the variable hidden_code inside brackets to use it.
I want to view the jupyter notebook in without having to execute, I mean no to open it and iteratively execute commands, just to see it as if it were a pdf or something like that.
I ask this because every time a want to see some code in the notebook I have to go to the specific directory and run the comand jupyter notebook and wait until it starts to be able to open the proper file.
If you are using Macos, give this a shot
Found in this thread:
A way to quick preview .ipynb files
You can view it nicely in PyCharm as well.
You can convert your notebook to html (or other formats) via
File -> Download as -> html
You can see them dropping the file on VSCode too.
i have installed vscode with official microsoft python package , every thing is ok except images rendering in markdown
i tried the following codes for displaying images in markdown cell :
<img src="images/grad_summary.png" style="width:600px;height:300px;">
alt
but it is not working although it is working on jupyter notebook
P.S.
vscode version: 1.40.1
python version : 3.7
vscode python extension version : 2019.10.44104
os : windows 10
Any Help :)
seems they have fixed it
#%%[markdown]
# 
%matplotlib inline
from IPython.display import Image
Image('image_path')
This is a known issue with local paths to images:
https://github.com/microsoft/vscode-python/issues/7704
Unfortunately there is no workaround.
As of 31/05/2022,
If you initially create the file in Jupyter Notebook and later open it in VC Code, the code for embedding the picture is:
Just delete 'attachment:' (to express the reference in the right format)
and the picture will load. (given the reference/path to it is still valid)
First you can drag a picture from VS Code file explorer and then dropping it in a Markdown cell holding shift button.
If you still have problems displaying the image, try to delete everything written in the file link except the picture's name. In your case you would have something like this:
<img src="images/grad_summary.png"> works for me now

works fine in Jupyter browser, but in VS Code and pycharm with Python extension it does not render at all, only a blank image box is shown. Both are running in the same conda environment.
This alternate method in a Markdown cell:
also works fine in Jupyter browser but does not render in VS Code with Python ext.
I searched stack overflow, there was something close but it did not address this issue. Any insights appreciated.
vocode broken image
We actually have an issue already reported with loading and showing local images. If you want to track our progress on fixing this issue you can follow our github issue here.

I created and saved a notebook using Jupyter notebooks. I then proceeded to create a github gist of this notebook. However, the notebook is not being rendered in the gist. I can only see the raw code. I have included the link to my gist below:
https://gist.github.com/adikamath/26ae33d4fd613d716cdf01697130e675
I know that GitHub provides advanced support for ipnyb since some time now and I don't have to use a service like nbviewer to see it rendered. Any help is appreciated.
I was able to make it work! Instead of copying the code from the .ipnyb file into the gist window, I dragged & dropped the whole file into the gist window and the gist renders it OK!
Just add.ipynb to gist file name. By default it saves as .txt file. Commit your file, you will be able to see it in form of jupyter notebook
Actually, I encountered a very similar problem, which did not change by copying or drag/dropping the file. The simple but somehow strange cure was to first close the jupyter notebook and then upload the notebook on gist (by drag&drop, but I think it does not matter).
The below steps worked for me:
create a new gist
drag and drop your .ipynb file into the window where your code should be placed.
give a name to your gist ending with .ipynb
create the gist
