Thanks for pointing that out! Now I got it to almost work. The epub is being generated and it contains images, but it seems to like using images where they shouldn't be (not like randomly adding images, but using the wrong image). Are there collisions between the images? If so, is that something one can fix?

The more recent pandoc-types should eliminate the need for
the orphan Semigroup instance.

You shouldn't need fillMediaBag if you're reading docx, because
the docx reader should populate the media bag automatically using
images from the docx container itself.

However, there's an issue with the way  your code is structured.
Each time you  do runIO, it will reinitialize the mediabag, so
you'll lose information.  What you should do is put the whole
conversion pipeline (reading docxs and writing epubs) under one runIO.
