After setting the Max width, the picture shows the problem.

[Jh623]

After I set the value of the Max width, if the width of the picture exceeds this value, there will be a large blank space under the picture.

I guess it should ideally shrink the size of the image to fit within the max width. This is a problem that can only be solved in Markmap though. Maybe you could create an issue there.

Ideally fixed in Markmap. Possible there's a workaround though.

I am not looking into customizing markmap too much. Maybe we can create a tag for closing these kind of issues and some documentation on how users should report their issues to markmap.
