Hello everone, Jupyter NoteBook can`t display image but same code works in Jupyter Lab.

My jupyter notebook version is 6.4.3

%%html <img src="1.jpg" />

In Chrome develop tool, network tab: Notebook requests url: http://<jupyter_url>/edit/1.jpg, with type text/html Lab requests http://<jupyter_url>/files/1.jpg, with type jpeg

downgrade to 5.5.0, everything works fine

Excuse me for cutting in, I have the same issue.

I use Jupyter. The Environmental is below.

and tried the test that is written in here (https://github.com/jupyter/nbclassic/issues/89)

I reproduce the same issue( can't see the local image file).

On the other hand, I downgrade Jupyter. The Environmental is below.

and tried the same test.

I can see the local image file.

Deriving from this, I think there were some changes between notebook versions 6.3.0 and 6.4.3. Is this correct behavior?

This fixes the analogous issue for nbclassic. https://github.com/jupyter/nbclassic/pull/148

I'm getting the same issue but downgrading notebook to 6.3.0 hasn't helped. I tried replicating @ivis-akaike 's environment and I get instead an internal issue with jinja (ImportError: cannot import name 'contextfilter' from 'jinja2').

I tried nbclassic's update, but it does not work for my environment.

so, I check image's path.「edit」 is still added to URL.

https://github.com/jupyter/nbclassic/pull/148 other command is needed to reflect this pull request?

@ericspod my emviroment with notebook 6.3.0 looks like works well. (dont show jinja2 error message.) I’m sorry I couldn’t be much of a help.

For reference this seems to be working fine with Notebook 7 (currently in beta):

Normally the fix should be available in nbclassic for the classic notebook UI. Which means this issue could probably be considered as fixed then.

[jtpio]

Closing as this should be fixed with the latest versions of Notebook 7, JupyterLab and NBClassic.

Please have a look at the documentation to learn how to run the different UIs on the same Jupyter Server: https://jupyter-notebook.readthedocs.io/en/latest/migrating/multiple-interfaces.html

Feel free to re-open or open a new issue if needed, thanks!

This does appear fixed in Notebook 7, thanks!
