I was trying https://ctan.org/pkg/transparent package. I get an error when using it with tex4ht. Same code works OK in lualatex and pdf.

Is there a way to make it work with tex4ht? Here is MWE

------------------------
\documentclass[12pt]{book}
\usepackage{graphicx}
\usepackage{transparent}
\begin{document}

some text here

More text here

\transparent{1}\includegraphics[width=0.5\textwidth]{example-image-a}

More text here

More text here
\end{document}
--------------------

Compiled using

make4ht -ulm default -a debug foo2.tex "mathjax,htm,nostyle"

gives

------------------------------
/usr/local/texlive/2023/texmf-dist/tex/latex/l3backend/l3backend-dvips.def)
(./foo2.aux) (/usr/local/texlive/2023/texmf-dist/tex/latex/base/ts1cmr.fd)

l.12 \transparent
{1}\includegraphics[width=0.5\textwidth]{example-image-a}
