The graphicx package has many example images, but where are they listed?
I can't find this feature in the package documentation.
\documentclass{article}
\usepackage{graphicx}
\begin{document}
\includegraphics{example-image}
\includegraphics{example-image-a}
\includegraphics{example-image-b}
\includegraphics{example-image-c}
\includegraphics{example-image-duck}
\end{document}
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.
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.
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}
%------------------------------------------

\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.

They are not provided by the
graphicxpackage but by themwepackage (look into thetex/latex/mwe/folder of your TeX distribution.example-image-duckon the other hand is provided byduckuments. As far as I know there is no comprehensive list showing all example images by packages.File list for TeX Live 2018 (example files provided by
