I've never used FPDF, but have you considered not doing the add_page
explicitly here?  The documentation at
https://pyfpdf.readthedocs.io/en/latest/reference/image/index.html might
be useful; see especially the behaviour specified when the "y" parameter
is not specified, as in this case.

If you're unable to resolve the issue, you should report it to pyfpdf at
https://github.com/reingart/pyfpdf/issues (after checking if this is a
known problem).
