I'm creating a leaflet and I use the leaflet package. I want to insert an image that fills 2 pages. Is there any option to set 3 separate pages for the front side of the paper and 2 (1 small, 1 double sized) pages for the back? I read through the documentation but I seem to have missed the part where the number of pages is set up. I read that up to 6 are possible. So I guess that fewer pages is also an option.
I want the front side to look like this

and the back side like this

Code:
\documentclass{leaflet}
\usepackage[ngerman]{babel}
\usepackage[utf8]{inputenc}
\usepackage{blindtext}
\usepackage{biolinum}
\renewcommand\rmdefault{\sfdefault}% Verwende serifenlose Schrift
\usepackage{mwe}% Dummy Bilder
\usepackage{xcolor}
\AddToBackground{1}{\put(0,0){\textcolor{blue!20}{\rule{\paperwidth}{\paperheight}}}}% Farbiger Hintergrund für 1. Seite
