list of filenames for figures

Question

i did read the following thread:

How to get a list of the filenames of the figures embedded in a document

and found myself in a similar problem. The actual problem is that the filenames printed by the accepted solution in the thread mentioned do not have any linking to the actual figure numbering. Ofcourse they occur in the order the figures do in the text. But I not only pass on the PDF produced I also do pass on the images included (or not) in the document just in case they got rendered unreadable by scaling, typesetting, low quality printouts, duplication of existing print versions etc. Therefor I do usually include a table that shows the number of the figure in one column and the filename in the next one. Just to make things 'idiot-proof'. Now the solution shown in the thread mentioned is very promising so far but how do I get the numbers in there automatically as well. Pressing it all into a 'tabular' should not be too hard in my opinion…

I am using pages like the one produced by this Code (although this may be the most extreme example through out the whole document)

Answer 1

Your example is the opposite of minimal. Regardless, I came across an answer on stackoverflow for retrieving each image filename (include the filename of a graphic into a caption?) which you can make use of.

To avoid having to change anything in your current files, you could redefine the \caption command in the preamble (the caption package won't like this however - see edit below for an alternative).

Code:

\documentclass{article}
\usepackage{graphicx} % \includegraphics
\usepackage{letltxmacro} % \LetLtxMacro
\usepackage{etoolbox} % \patchcmd

% Source: https://stackoverflow.com/questions/3736292/in-latex-is-there-a-way-to-include-the-filename-of-a-graphic-into-a-caption
\makeatletter
\patchcmd{\Gin@setfile}% <cmd>
  {\ProvidesFile}% <search>
  {\xdef\imgfilename{#3}\ProvidesFile}% <replace>
  {}{}% <success><failure>
\makeatother
% Redefine caption to save us having to manually add the \write to each figure
\LetLtxMacro{\OldCaption}{\caption}
\renewcommand{\caption}[1]{%
    \OldCaption{#1}%
    \immediate\write\tempfile{Figure \thefigure: \imgfilename\space (page \thepage)}%
}
% Open output stream
\newwrite\tempfile
\immediate\openout\tempfile=figurelist.txt
\begin{document}
\begin{figure}
  \centering
  \includegraphics[width=.5\linewidth]{foo.png}
  \caption{My caption}
\end{figure}
\clearpage
\begin{figure}
  \centering
  \includegraphics[width=.5\linewidth]{bar.png}
  \caption{My caption}
\end{figure}
% Close output stream
\immediate\closeout\tempfile
\end{document}

Output (figurelist.txt):

Figure 1: foo.png(page 1)
Figure 2: bar.png(page 2)

Edit:

As pointed out in a comment, this will also try to add file names if a caption is used in another type of float environment (e.g. table), which is probably not what you want (\imgfilename will hold the last actual file name and so you will see duplicates in figurelist.txt). A better solution would be a custom caption command that you use in figures with images only:

% Alternative - define a new type of caption to use in figures with grpahics
\newcommand\imgcaption[1][]{%
    \caption{}%
    \immediate\write\tempfile{Figure \thefigure: \imgfilename\space (page \thepage)}%
}

Answer 2

Here's a slightly different way of doing things which integrates the list into the document more seamlessly. The basic idea is to create a new \listofimages and then make a command the goes inside the figure caption to add the entry.

\documentclass{article}
\usepackage{graphicx}
\usepackage[T1]{fontenc} % not needed for LuaTeX or XeLaTeX
\usepackage{letltxmacro}
\usepackage{tocloft}
% make a new list of image filenames
\newlistof{images}{img}{List of Filenames}
\renewcommand{\cftimgtitlefont}{\normalfont\bfseries\Large}
% redefine \includegraphics to save the filename inserted
\LetLtxMacro{\OldIncludegraphics}{\includegraphics}
\renewcommand{\includegraphics}[2][]{%
    \gdef\CurrentImage{#2}%
    \OldIncludegraphics[#1]{#2}%
}
% make a command to add to the list of images
% since this will be inserted into the caption command, we check for the figure environment
%
\makeatletter
\newcommand{\Img}{\def\@tmp{figure}\ifx\@tmp\@currenvir\addcontentsline{img}{images}{Figure \thefigure. \texttt{\protect\detokenize{\CurrentImage}}}\else\relax\fi}
\makeatother
% redefine caption to add \Img command
% technique here from https://tex.stackexchange.com/a/97279/
\LetLtxMacro{\OldCaption}{\caption}
\renewcommand{\caption}[2][]{%
    \if\relax\detokenize{#1}\relax
    \OldCaption{#2}\Img
    \else
    \OldCaption[#1]{#2}\Img
    \fi}

\begin{document}
\listoffigures
\listofimages
\clearpage
\begin{figure}
\includegraphics[width=.2\linewidth]{example-image-a.pdf}
\caption{Example Image A}
\end{figure}

\begin{figure}
\includegraphics[width=.2\linewidth]{example-image-c.pdf}
\caption{Example Image C}
\end{figure}
