Not yet :-) THis is designed for images that are generated through 
executable fold environments, like in

https://texmacs.github.io/notes/docs/embedding-tikz-figures-short.html.

It works on a tree (TeXmacs syntax unit) that contains an image, and it 
has to be executed with its keyboard shortcut. I do not yet know how to 
execute it automatically.

For all other images, I have to work on that, and maybe for inserting 
images the solution is different.

Pls. give me some time to think---if I find a general solution for 
changing the default width of images, I will post it.
