Multicols with includegraphics in bottom of the page

Question

In my document i have a picture in a multicols env.

The problem is that Latex put the multicols in the bottom of the page and the picture is going under the footer. Latex should create a new page. Can you help me ?

thank you

Here is a demo code

Edit MWE

\documentclass[a4paper]{article}
\usepackage{geometry}
\usepackage{multicol}
\usepackage{graphicx}
\usepackage{lipsum}

\geometry{a4paper, portrait, left=2cm, top=1cm, right=2cm, bottom=2cm}

\begin{document}
\section{Etape : 1}
\lipsum[1-5]

\section{Etape : 2}
\begin{multicols}{2}
     \includegraphics[width=10cm]{example-image}

\vfill
\columnbreak
text text text 
\end{multicols}

\section{Etape : 3}
\begin{multicols}{2}
     \includegraphics[width=10cm]{example-image}

\vfill
\columnbreak
text text text 
\end{multicols}
\end{document}

Answer 1

Here is a solution. the multicols environment has two optional arguments

\begin{multicols}{columns}[text in full width][vertical space at least]

\documentclass[a4paper]{article}
\usepackage{geometry}
\usepackage{multicol}
\usepackage{graphicx}
\usepackage{lipsum}

\geometry{a4paper, portrait, left=2cm, top=1cm, right=2cm, bottom=2cm}

\newsavebox\mt

\begin{document}
\section{Etape : 1}
\lipsum[1-5]


\sbox\mt{\parbox{\textwidth}{\section{Etape : 2}\includegraphics[width=10cm]{example-image}}}
\begin{multicols}{2}[\section{Etape : 2}][\ht\mt]
\includegraphics[width=10cm]{example-image}
\vfill
\columnbreak
text text text 
\end{multicols}


\sbox\mt{\parbox{\textwidth}{\section{Etape : 3}\includegraphics[width=10cm]{example-image}}}
\begin{multicols}{2}[\section{Etape : 3}][\ht\mt]
\includegraphics[width=10cm]{example-image}
\vfill
\columnbreak
text text text 
\end{multicols}
\end{document}
