How to size images?

How to size images?

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/...}
