how do I draw text above images using the background package?

Question

I am working on repeating a watermark as answered here. Using that approach I find the drawn background always appears below images added using \includegraphics. Take the following document:

\documentclass{scrartcl}
\usepackage{background}
\usepackage{lipsum}

\backgroundsetup{
  color=red,
  angle=45,
  opacity=.8,
  contents={\large{Hellow World}}
}

\begin{document}
\lipsum[1-2]
\begin{center}
\includegraphics[width=5cm]{wikimedia}
\end{center}
\lipsum[2]
\end{document}

Rendering a PDF with tectonic works but the image added always appears on top:

Is there a way to configure background package or another setting so that the Hello World text below always appears on top of everything in the document? I do realize that the name of the package suggests otherwise.

Or should I invest more time solving this with KOMA Script's scrlayer-scrpage or another alternative?

Answer 1

Well the background package uses the everypage package, at this package is only about adding background material.

I personally prefer to use the eso-pic package (also because background uses a tikzpicture which makes it difficult to use them in the material). But if you want to stay with background you could try to tweak background:

\documentclass{scrartcl}
\usepackage{background}
\usepackage{lipsum}
\usepackage{eso-pic}
\makeatletter
\let \AddEverypageHook \AddToShipoutPictureFG
\renewcommand\AddThispageHook{\AddToShipoutPictureFG*}
\ifbg@some
  \AddThispageHook{}
\else
  \AddEverypageHook{\bg@material}
\fi
\makeatother

\backgroundsetup{
  color=red,
  angle=45,
  opacity=.8,
  contents={\large{Hellow World}},
}

\begin{document}
\lipsum[1-2]
\begin{center}
\includegraphics[width=5cm]{example-image-duck}
\end{center}
\lipsum[2]
\end{document}
