insérer des images sans distance verticale dans (la-) tex

Question

J'essaie cela, mais je prends un peu de distance.

\documentclass{article} 
\usepackage{graphicx} 
\usepackage[a3paper,landscape]{geometry} 
\begin{document} 

\includegraphics[width=5cm, height=5cm]{1.png}\includegraphics[width=5cm, height=5cm]{1.png}\includegraphics[width=5cm, height=5cm]{1.png}\includegraphics[width=5cm, height=5cm]{1.png} 

\includegraphics[width=5cm, height=5cm]{1.png}\includegraphics[width=5cm, height=5cm]{1.png}\includegraphics[width=5cm, height=5cm]{1.png}\includegraphics[width=5cm, height=5cm]{1.png} 

\includegraphics[width=5cm, height=5cm]{1.png}\includegraphics[width=5cm, height=5cm]{1.png}\includegraphics[width=5cm, height=5cm]{1.png}\includegraphics[width=5cm, height=5cm]{1.png} 

\includegraphics[width=5cm, height=5cm]{1.png}\includegraphics[width=5cm, height=5cm]{1.png}\includegraphics[width=5cm, height=5cm]{1.png}\includegraphics[width=5cm, height=5cm]{1.png} 


\end{document}

Modifier comme ceci:

\includegraphics[width=5cm, height=5cm]{1.png}\hspace*{-1pt}\includegraphics[width=5cm, height=5cm]{1.png}\hspace*{-1pt}\includegraphics[width=5cm, height=5cm]{1.png}
