Markdown image for valid image paths does not render

[choldgraf]

I'm not sure what the issue here is, but I've found that paths to valid images do not render properly with Markdown and I'm not sure why.

For example, below I show that an image exists by displaying it with IPython.display.Image, but show that it does not exist if I try to display the same image using markdown with jupyterlab-myst:

This also doesn't work for relative paths:

Possibly related, embeds are not working in the notebook.

Interestingly, the two forms of embeds fail in different ways.

I've just run into this as well (jupyterlab-myst 2.4.2):

Does not render:

![logo](../../scipy2024.png)

<img src="../../scipy2024.png" align="right" width="20%">

Does render (full URL)

<img src="https://github.com/xarray-contrib/xarray-tutorial/blob/main/images/scipy2024.png?raw=true" align="right" width="20%">

Does render if image in same directory as notebook but does not align as expected :(

```{image} ./scipy2024.png
:alt: ScipyLogo
:width: 20%
:align: right
``` 

Does not render if image in a parent directory

```{image} ../../scipy2024.png
:alt: ScipyLogo
:width: 20%
:align: right
``` 

But we have lots of notebooks with local paths in a github repository. It would be nice if this were supported so that the notebook appears in JupyterLab exactly as it does on a website, for example:
https://github.com/xarray-contrib/xarray-tutorial/blob/main/workshops/scipy2024/index.ipynb

@scottyhq can you confirm where the root directory of the Jupyter server is? I.e the path to the top-level directory in the jupyterlab file browser. The problem described above is a fundamental challenge that follows from Jupyter kernels using a different file system interface (kernel process) to the Jupyter frontend (E.g jupyterlab via Jupyter server).

I'm closing this because I'm pretty sure this is due to user expectations rather than a bug in our code. I recognise that this can be confusing, and/or I might be wrong, so please do ping back here if you want to continue the conversation! <3
