There is an excellent [answer](https://tex.stackexchange.com/a/108117) to a very similar question already. I tried to adapt it to my use case: 6 1/4" x 9" paper. But doing so added empty pages at the end of each chapter, before the illustrations. What am I doing wrong?

```
    \documentclass[12pt,smallroyalvopaper]{memoir}
    \usepackage{lipsum}
    \usepackage{graphicx}
    \usepackage[left=0.75in, right=0.875in, top=0.75in, bottom=0.75in]{geometry}

    \usepackage{mwe}

    \newcommand\chapimage[1]{%
    \cleartoverso 
    \noindent\begin{picture}(0,0)%
    \put(-55,-585){%
    \includegraphics[width=0.95\stockwidth,height=0.95\stockheight]{#1}}%
    \end{picture}
    \clearpage}

    \begin{document}

    \chapimage{example-image-a}% don't use extension
    \chapter{Title ch1}%

    \lipsum[1-3]

    \chapimage{example-image-b}
    \chapter{Title ch2}%

    \lipsum[2-4]

    \chapimage{example-image-c}
    \chapter{Title ch2}%

    \lipsum[3-5]

    \end{document}

```

Edit:

This is the output with `\cleartorecto`
