Odd or even full-page float

Question

I want to place a full-page image after one of the closest page breaks, but I want to control, whether to place this image on ad odd or on an even page.

The closest question I found is this: Dynamically insert full-page image at nearest page break.

Probably I should use something like this:

    \newcommand{\placeonodd}[1]{%
        \ifeven\c@page{
            \afterpage{
            \thispagestyle{empty}\noindent\includegraphics[height=\textheight]{#1}%
            }}
        \else{---somehow delay \includegraphics until next pagebreak---}
    }

Answer 1

Were you getting \ifeven from some package?

\documentclass{article}
\usepackage{afterpage}
\usepackage{mwe}

\newcommand{\placeonodd}[1]{%
  \ifodd\value{page}\afterpage{\placeonodd{#1}}%
  \else\afterpage{\thispagestyle{empty}\noindent%
    \includegraphics[height=\textheight,width=\textwidth]{#1}}%
  \fi
}
\begin{document}
\placeonodd{example-image}
\lipsum[1-16]
\end{document}
