Re: [O] HTML/images zipped?

[John Kitchin]

hm... maybe it has been a while since I ran that ;) I pushed some
changes that seem to have it working on a small test file.

This code is somewhat on the border of a filter/custom export. There are
probably links that will now work with it, I have not tested it super
thoroughly.

Notably, it does not preserve relative paths, but rather renames files
and images and replaces the links in the org-file with the new
names. It was too hard to figure out how to preserve the paths when I
wrote this originally.
