When I process a markdown file with an image to pdf, using groff -t ms -o text.pdf text.md, instead of an image I just get a text in square brackets saying [IMAGE: (description)]. The identical document processed via LaTeX (using groff -o text.pdf text.md) includes the image.

I looked at the intermediate groff -ms file. That has the text [IMAGE: (description)] instead of .PSPIC requests.

Using pandoc 3.1, on crostini on a Chromebook.

In the attached files, the extension of the image filename has to be .eps for groff outout, .png for LaTeX.
