Image attachment not shown when converting to PDF

[t-makaro]

image_test.ipynb.zip

Running Jupyter nbconvert --to pdf image_test.ipynb on a notebook with an attachment ![image.png](attachment:image.png), the resulting image is not shown. Similar too #699.

In nbconvert 5.5 a pdf is still produced, after #1053 this throws an error.

I am facing the same issue, any solution or workaround?

Also by doing this in a Markdown cell:

\begin{figure}[h!]
\includegraphics{myImage.png}
\end{figure}

the exported PDF does not show any image, but an empty blank space instead, by the look of it exactly of the size of the image.

Okay folks--finding no other way, I ended up breaking down my markdown cells as markdown--python--markdown cells with the middle one as:

from IPython.display import display, Image
display(Image(filename="a.png", height=400, width=400))

Now jupyter-nbconvert --to PDFviaHTML notebook.ipynb properly converts to notebook.pdf.

Struggling with this to brand jupyter notebook output with a logo

@tashrifbillah Thank you for your solution! This worked for me. Hopefully this is resolved soon as this is a pretty common use case.

i don't think this is a PDF exporting issue only, for me HTML export with images that were pasted into markdown (attached to cell metadata) also doesn't work...

from what i can tell this seems related to #1057 and seems to have been fixed after #699, #780, #980 ...
is this maybe a regression?

[tuncbkose]

Should be fixed with #1978. Please reopen if there are any issues

I'm still facing this problem. Is this fix already released?

Inserting an image to a Markdown cell using either of the two following ways does not work

![Circadian rhythm](../data/doc/circadian-rhythm-collage.jpg)
<img src="./data/doc/circadian-rhythm-collage.jpg" alt = "Circadian rhythm">

Also dropping the image into the same folder as the notebook (to avoid the need of a relative paths) doesn't help.

See how the result is displayed:

I convert the Jupyter notebook using the following command:

jupyter nbconvert --to pdfviahtml file.ipynb

I'm running the following versions (no idea what is really relevant):

• Python 3.10.5
• Jupyter 1.0.0
• nbconvert 7.16.2
• nbclient 0.9.0
• nbclassic 1.0.0
• nbformat 5.9.2
• notebook 7.1.1
• notebook-as-pdf 0.5.0

The fix above applies to PDF generation via LaTeX (--to pdf). Does that work for you?

I don't exactly remember the state of PDF via HTML because I didn't use it much. Also are your relative paths the same? You have both ./data/ and ../data/.

[normanius]

My bad, I was confusing those. With --to pdf it works.

Is that a known issue, or should I report the problem in a separate issue?

[tuncbkose]

#1938 is the same issue, you could leave a comment/reaction if you'd like.

[normanius]

Okay. Thanks. Will do it.

Convert that image to base64 and then pass it.

import base64
with open("numpylogo.jpeg", "rb") as img:
    img_data = str(base64.b64encode(img.read()))[2:-1]

now just print that. then copy that huge string (without the single quotes), and replace it where you want to see the markdown image:

![image](data:image/jpeg;base64,that_big_base64_content)

remove that that_big_base64_content and paste your content (after the comma), and run.

This worked for me
