The trick is to put your graphics in a \vcenter
box. The rest is just bureaucracy: \vcenter
requires math mode, and \hbox
prevents the image from taking the whole line width.
\documentclass{article}
\usepackage{graphics}
\newcommand\myincludegraphics[1]{%
\ensuremath{\vcenter{\hbox{\includegraphics{#1}}}}%
}
\begin{document}
\begin{figure}
\centering
\renewcommand\arraystretch{3}
\begin{tabular}{rcl}
description&\myincludegraphics{gfx/test}&description\\
description&\myincludegraphics{gfx/test}&description\\
description&\myincludegraphics{gfx/test}&description\\
description&\myincludegraphics{gfx/test}&description\\
&0\hfill 5\hfill\hfill 15\hfill\hfill\hfill 30&min
\end{tabular}
\caption{A caption}
\label{fig:figure}
\end{figure}
\end{document}
EDIT: This version deals with descriptions of different lengths, keeping the images horizontally centered no matter what.
The main idea is to put the left descriptions in a \llap
(so it will stick out to the left, while pretending to 0pt
wide) and the right descriptions in a \hbox to 0pt
(these will pretend to be 0pt
wide but stick out to the right --- by the way, \rlap
doesn't work well in this case).
The rest is to make things easy to use. Package array
allows to you automatically but arbitrary code around your entries using <
and >
. Furthermore, it allows you to define new column types. So I put all the \llap
and \hbox
magic in the column type C
, and included the vertical positioning magic in there as well. This should make things easier to use.
Since the middle column type was redefined, the old timeline didn't work anymore, so I used \multicolumn
to reset the middle column type for the last line back to a simple c
. While at it, I have packed it all in a macro to save some further typing. (Maybe we should make it extremely fancy by making LaTeX position the numbers on the timeline automatically? :-))))

UPDATE 2: Automatic tick-placement (for fun) and fixed intercolumn spacing (for real):

\def\firstT#1{\makebox[0pt][c]{#1}\xdef\previousT{#1}\global\let\do\otherTs}

UPDATE: left-aligned left description
I don't know how to do this automatically, because one needs to know the width of the widest left description in advance. A semi-automatic solution is to set this length in advance, just before the tabular
environment --- the column definiton then puts the left description in a \hbox
of the given width.
\documentclass{article}
\usepackage{graphicx}
\usepackage{array}
\newlength\widestLeftEntryLength
\newcolumntype{C}{%
>{\llap\bgroup\hbox to \widestLeftEntryLength\bgroup}c<{\hss\egroup\egroup\hskip 1em}%
@{}>{$\vcenter\bgroup\hbox\bgroup}c<{\egroup\egroup$}@{}
>{\hskip 1em\hbox to 0pt\bgroup}c<{\egroup}%
}%
\begin{document}
\begin{figure}

\renewcommand\arraystretch{3}
\settowidth\widestLeftEntryLength{description very very extremely long}

Best Answer
This solution only places unnumbered subtext below the figures, just using a separate figure row. If there is no text on the same row with the figures, then a
\raisebox
approach is not required. Since you didn't provide a minimum working example (MWE), I assumed that the figures were on a row by themselves. I omitted\hline
between the titles, the figures, and the subtext, so as to group them more nicely. By usingp
columns, text wraps automatically.As David pointed out, one must leave room for column padding separation, so in this case, I only made each column width
0.21\textwidth
to avoid overfilling the column width.To answer the OP's follow-up, on how to add gap between an
\hline
and a subsequent row of\includegraphics
images, which are otherwise flush with the\hline
, there are many approaches. The one I adopt is to use the\addvbuffer[top_gap bottom_gap]{...}
macro from myverbatimbox
package. One merely need apply this to the tallest image of the row. Here, I re-present the MWE with the\hline
s added, and an\addvbuffer
in place.
