Simplify code for repeating same image

graphicsloops

I want to print an image in the layout,

My current code:

\documentclass{article}
\usepackage{graphicx}
\usepackage{blindtext}
\usepackage{showframe}
\begin{document}
\begin{center}
\includegraphics[width=.3\linewidth]{example-image-a}\quad\includegraphics[width=.3\linewidth]{example-image-a}\quad\includegraphics[width=.3\linewidth]{example-image-a}\quad
\\[\baselineskip]% adds vertical line spacing
\includegraphics[width=.3\linewidth]{example-image-a}\quad\includegraphics[width=.3\linewidth]{example-image-a}\quad\includegraphics[width=.3\linewidth]{example-image-a} \quad
\includegraphics[width=.3\linewidth]{example-image-a}\quad\includegraphics[width=.3\linewidth]{example-image-a}\quad\includegraphics[width=.3\linewidth]{example-image-a} \quad
\includegraphics[width=.3\linewidth]{example-image-a}\quad\includegraphics[width=.3\linewidth]{example-image-a}\quad\includegraphics[width=.3\linewidth]{example-image-a} \quad
\includegraphics[width=.3\linewidth]{example-image-a}\quad\includegraphics[width=.3\linewidth]{example-image-a}\quad\includegraphics[width=.3\linewidth]{example-image-a} \quad
\includegraphics[width=.3\linewidth]{example-image-a}\quad\includegraphics[width=.3\linewidth]{example-image-a}\quad\includegraphics[width=.3\linewidth]{example-image-a} \quad
\includegraphics[width=.3\linewidth]{example-image-a}\quad\includegraphics[width=.3\linewidth]{example-image-a}\quad\includegraphics[width=.3\linewidth]{example-image-a}
\end{center}
\end{document}

My output:

How can I simplify my code, so that I don't need to copy and paste \includegraphics multiple times. An example would be a loop or for-each command.

A fairly general \repeatthings command. It has five arguments:

the number of repeats
(optional) the modulo
the thing to repeat
what to place between items
(optional) what to place at the modulo

Nothing is added at the end.

\documentclass{article}
\usepackage{graphicx}

\ExplSyntaxOn
\NewDocumentCommand{\repeatthings}{m o m +m +O{}}
 {% #1 = number of repeats
  % #2 = optional modulo
  % #3 = thing to repeat
  % #4 = what to put in between
  % #5 = what to put at chunks specified by #2
  \IfNoValueTF { #2 }
   {
    \latexforti_repeat:nnn { #1 } { #3 } { #4 }
   }
   {
    \latexforti_repeat:nnnnn { #1 } { #2 } { #3 } { #4 } { #5 }
   }
 }

\cs_new_protected:Nn \latexforti_repeat:nnn
 {% no modulo
  \int_step_inline:nn { #1 - 1 }
   {
    #2 #3
   }
  #2
 }

\cs_new_protected:Nn \latexforti_repeat:nnnnn
 {
  \int_step_inline:nn { #1 - 1 }
   {
    #3
    \int_compare:nTF { \int_mod:nn { ##1 } { #2 } = 0 } { #5 } { #4 }
   }
   #3
 }
\ExplSyntaxOff

\begin{document}

\begin{center}
\repeatthings{18}[3]{\includegraphics[width=.3\linewidth]{example-image-a}}{\quad}[\\[1ex]]
\end{center}

\clearpage

\repeatthings{20}{I must not drive the principal's car}{\par}

\bigskip

\repeatthings{20}[5]{I must not crash the principal's car}{\par}[\par\medskip]

\end{document}

[Tex/LaTex] Conflict between color, graphicx and libertine

These option clashes happen when a package is requested to be loaded on two different positions, like by you and inside another package, but with different options. The package is loaded by the first \usepackage (or its twin \RequirePackage); it isn't loaded again when it is requested again. It simply can't be loaded a second time. Therefore the new options can be activated and previous options might conflict with the second usage. So LaTeX creates an error to report this issue to you.

The way to fix this is to declare the options beforehand using \PassOptionsToPackage{<options>}{<package>}. Then they are used wherever the package is loaded.

\documentclass{article}
\usepackage{ifpdf}
\ifpdf
    \PassOptionsToPackage{pdftex,usenames,dvipsnames}{color}
    \usepackage[T1]{fontenc}
    \usepackage{libertine} % most likely loads 'color' itself
    %\usepackage{lmodern} % doesn't load 'color'
    \usepackage{color}
    \usepackage[pdftex]{graphicx}
\else
    %\bye
\fi
\begin{document}
Hello, world!
\end{document}

I can't test it by myself, because I don't have the libertine package installed.

PS:

I don't think you need to set pdftex manually. Normally packages do a good job recognizing the driver by themselves. Also you might want to use the extended xcolor package instead of color.

[Tex/LaTex] Two figures side by side with text wrapping

You have to carefully adjust the dimensions of your image and the number of lines the wrap figure will extend ( for example [10] in \begin{wrapfigure}[10]{r}{5.5cm}).

An example:

\documentclass{article}
\usepackage{graphicx,wrapfig,lipsum}
%------------------------------------------
\begin{document}
This is where the table goes with text wrapping around it. You may
embed tabular environment inside wraptable environment and customize as you like.
%------------------------------------------
\begin{wrapfigure}[10]{r}{5.5cm}
\rule{5.5cm}{7.1cm}
\caption{A wrapped figure}\label{wrap-fig:1}
\end{wrapfigure}
%------------------------------------------
This is where the table goes with text wrapping around it. You may
embed tabular environment inside wraptable environment and customize as you like. This is where the table goes with text wrapping around it. You may

%
\begin{figure}[h]
\begin{minipage}{6cm}
\centering
\rule{\textwidth}{3cm}
\caption{my figure}\label{fig:2}
\end{minipage}%
\end{figure}%

\lipsum[2-3]

Figure~\ref{wrap-fig:1} is a wrapped figure.

\end{document}
