setting graphics' path

Source

  • instead of using

    \includegraphics[width=\textwidth]{folder2_relative/picture.png}%

  • by including in the front matter (i.e. before \begin{document}):

    \DeclareGraphicsExtensions{.png,.pdf}%
\graphicspath{{../folder1_relative/},{folder2_relative/},{/home/myname/folder_absolute/figures/}}%

  • you may simply use

    \includegraphics[width=.49\textwidth]{picture}%

  • one advantage is that you could use context dependent rules, for instance:

    \newif\ifpdf
   \ifx\pdfoutput\undefined \pdffalse
\else \pdfoutput=1 \pdftrue \fi
% portability between LaTeX and pdfLaTeX
\ifpdf
\usepackage[pdftex]{graphicx}
\usepackage[pdftex, pdfusetitle ,colorlinks=false, pdfborder={0 0 0}]{hyperref}%
\DeclareGraphicsExtensions{.png,.pdf}%
\graphicspath{{figures_pdf/}}%
\pdfoutput=1 % we are running pdflatex
\pdfcompresslevel=9     % compression level for text and image;
\pdftrue
% we are using the traditional latex
\else
\usepackage{graphicx}%
\usepackage[colorlinks=false]{hyperref}%
\DeclareGraphicsExtensions{.eps}%
\graphicspath{{figures_eps/}}%
\fi
