I'm writing a technical manual and I'm using this template:

\end{document}

I want to add some picture, quite big, and I'm looking for how to use a different margin for the pictures so as to display larger images.

Thaks for the help.

Answer 1

like this:

with help of package changepage:

\documentclass[twoside,a4paper]{refart}
\usepackage{makeidx}
\usepackage{ifthen}
% ifthen wird vom Bild von N.Beebe gebraucht!
\usepackage[demo]{graphicx}         %%%% added, in real document delete option "demo"
\usepackage[strict]{changepage}     %%%% added

\def\bs{\char'134 } % backslash in \tt font.
\newcommand{\ie}{i.\,e.,}
\newcommand{\eg}{e.\,g..}
\DeclareRobustCommand\cs[1]{\texttt{\char`\\#1}}
