removing images from epub for typst/pdf conversion

[jarnowic]

Hello! How can I remove images from epubs in converting to pdf via typst? groff-ms removes images automatically, but typst tries to render them.

C:\Downloads>pandoc -o carroll72img.pdf -t typst carroll72img.epub
error: file not found (searched at \\?\C:\Downloads\6012930945704010388_cover.jpg)

    │            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Error producing PDF.

Using --extract-media . in the CL includes the images, but I only need the placeholders, considering that I may be downloading content from URLs, and a known vulnerability .

There might be a Lua filter to remove image references, but I can't find it.

carroll72img.epub was downloaded from https://gutenberg.org/ebooks/12 and renamed to make it intelligible.

This Lua filter should do:

funtion Image (img)
    return img.caption
end

It replaces the image with the image caption. One could also use return img.src to use the image path as the placeholder.
