This worked fine. Now the file won't be generated each time. OTOH, if we change CL we will have to remember to regenerate it.

Can't you instead simply add the generated files to.gitignore? AFAIK this does not affect the already commited version.

Advantages:

• It's simpler to update because the files are always generated. Otherwise you'd have to copy the code and run it somewhere.
• One might even add a script to automatically check if the generated image is still matching the one in the repository.

For some reason the files don't regenerate in the same spot if I just remove them from the repo. Any idea what the new static link should be?

i.e. the link/_static/constrained_layout/CL02.png is invalid.

Thanks for suggestion@timhoffm - it was a struggle, but I finally got it to work...

Well the sphinx folks said we should write a png "scraper" to copy the file over, and get it included in the written rst. If it is a useful feature elsewhere, I'm happy to implement it. It didn't seem that hard, and basically is what you suggest here...

Working for now. If there is interest in writing a scrapper, that can always be done later.
