How can I create different content slides? - latex

Question

I know how to create different backgrounds for title slides with
\defbeamertemplate{background}{title_horizontal}{
...
}
then assign them to the title page (and remove footline for title) with
\def\ps#titlepage#horizontal{%
\setbeamertemplate{background}[title_horizontal]
\setbeamertemplate{footline}{}
}
and then create a text layout with matching background with
\defbeamertemplate*{title page}{custom}[1]{
\ifthenelse{\equal{#1}{horizontal}}
{
\thispagestyle{titlepage#horizontal}
}{}
...
}
and use them in the document with
\setbeamertemplate{title page}[custom][horizontal]
However, I was not able to find anything about how to create and select different layouts of normal content slides.
Is it possible to create different layouts for normal content slides in a similar way?
What is the keyword for content slides?

You could use the same technique as in https://topanswers.xyz/tex?q=1162#a1369 :
\documentclass{beamer}
\usepackage{tikz}
\makeatletter
\defbeamertemplate{background canvas}{image}[1][]{%
\begin{tikzpicture}[remember picture,overlay,inner sep=0pt,outer sep=0pt]
\node[anchor=east] at (current page.east) {\includegraphics[height=\paperheight]{#1}};
\end{tikzpicture}%
}
\BeforeBeginEnvironment{frame}{%
\setbeamertemplate{background canvas}[default]%
}
\makeatletter
\define#key{beamerframe}{myimage}[]{
\setbeamertemplate{background canvas}[image][#1]%
}
\makeatother
\begin{document}
\begin{frame}[plain,myimage=example-image-golden-upright]
\begin{columns}[onlytextwidth]
\begin{column}{.5\textwidth}
image frame
\end{column}
\begin{column}{.5\textwidth}
\end{column}
\end{columns}
\end{frame}
\begin{frame}
regular
\end{frame}
\end{document}
