Image broken in 'src-ref' documentation
For example if you visit https://src-ref.docs.torproject.org/tor/dataflow.html, the "structure hierarchy for connection types" image is missing (the img tag has a 404). There are possibly other missing images as well, but I can't find the markdown files to check (there were the original versions, then they were moved to the tor git repo and edited iirc, but now they're gone).
There's also another image missing on the same page, but has no tag (compare the top of the https://people.torproject.org/~nickm/tor-auto/internal/02-dataflow.html and https://src-ref.docs.torproject.org/tor/dataflow.html pages). But it may have been removed on purpose.
