Within Jupyter markdown cells, jpeg images can be referenced like
![](image.jpg) or like <img src=”image.jpg” width=600>. Then convert from
Jupyter to LaTex. The former approach does not allow for image sizing.
The latter approach results in ignored HTML.
Is there a way, perhaps with a lua filter, to capture the <img
src=”image.jpg” width=600> with the sizing information and transform it to
\includegraphics[width=……,height=……]{images/image.jpg} ? Or is there some
other preferred way to size images?

Lua filter to do this:
``` lua
function RawInline (raw)
if raw.format:match 'html' then
return pandoc.utils.blocks_to_inlines(
pandoc.read(raw.text, 'html').blocks
)
end
end
```
This tries to convert *all* inline HTML code. Modify the `if` condition
in case you want this behavior only for images:
if raw.text:match '^<img' and ...

Thanks, that works well.
Another solution I've come to is to just display jpeg's from code cells
rather than from markdown cells, like this: display_jpeg(file="img.jpg",
width=400). pandoc's normal behavior then just converts the sized image to
\includegraphics[width=..., height=...]{images/...}
