I have a table with four images.

begin{table}[ht]

caption{table caption...}

centering

begin{tabular}{cc}

includegraphics[width=45mm]{w.png} &includegraphics[width=45mm]{x.png}\

newline

includegraphics[width=45mm]{y.png}&includegraphics[width=45mm]{z.png}\

end{tabular}

end{table}

I want to caption each of the images. Normally I would do this by placing includegraphics within a begin{figure} block using caption{...}. But when I do this, the images disappear.

What is the proper way to do this, so that I can caption each of the images.

Or you could use the subfig package:

usepackage{subfig}



...



begin{figure}

  centering

  subfloat[Caption 1]{label{ref_label1}includegraphics[width=0.5textwidth]{path/to/figure1}}

  subfloat[Caption 2]{label{ref_label2}includegraphics[width=0.5textwidth]{path/to/figure1}}

  caption{label{ref_label_overall}Overall caption}

end{figure}

You can use the subcaption package for this but I think you don't need table for such use. You can embed everything into a general figure environment and place them as you wish. See the manual for that. Here is the version with Table.

documentclass{article}

usepackage{mwe} % For dummy images

usepackage{subcaption}

begin{document}

{centering

begin{table}[ht]

begin{tabular}{cc}

begin{subfigure}{0.4textwidth}centeringincludegraphics[width=0.3columnwidth]{example-image-a}caption{Figure A}label{fig:taba}end{subfigure}&

begin{subfigure}{0.4textwidth}centeringincludegraphics[width=0.3columnwidth]{example-image-b}caption{Figure B}label{fig:tabb}end{subfigure}\

newline

begin{subfigure}{0.4textwidth}centeringincludegraphics[width=0.3columnwidth]{example-image-c}caption{Figure C}label{fig:tabc}end{subfigure}&

begin{subfigure}{0.4textwidth}centeringincludegraphics[width=0.3columnwidth]{example-image-a}caption{Figure A again}label{fig:taba2}end{subfigure}\

end{tabular}

caption{A table with figures}

label{tab:mytable}

end{table}

}



We can see that Figure ref{fig:taba} and Figure ref{fig:taba2} is the same. Also the table counter value is used for the reference.

end{document}

You could simply use capt-of which provides stand-alone captionof command

documentclass{book}

usepackage[demo]{graphicx}

usepackage{capt-of}

usepackage{tabu}



begin{document}



begin{table}[ht]

caption{Simple but not clever}

centering

begin{tabu}to textwidth {X[c]X[c]}

  includegraphics[width=45mm]{w.png}captionof{figure}{fd} &includegraphics[width=45mm]{x.png}captionof{figure}{fd} \

  includegraphics[width=45mm]{y.png}captionof{figure}{fd} &includegraphics[width=45mm]{z.png}captionof{figure}{fd} \

end{tabu}

end{table}



end{document}

This has two disadvantages: first it's not elegant and the table caption is much to close to the first picture. In my opinion one of the subfig or subcaption solutions is much better. When using a KOMA class there is no need to load capt-of.

Building off of a previous answer, if you want to use the subfig package with multiple rows:

usepackage{subfig}



...



begin{figure}

  centering

  subfloat[Caption 1]{label{ref_label1}includegraphics[width=0.5textwidth]{path/to/figure1}}

  subfloat[Caption 2]{label{ref_label2}includegraphics[width=0.5textwidth]{path/to/figure1}}

  % leave a blank space for a new row



  subfloat[Caption 3]{label{ref_label3}includegraphics[width=0.5textwidth]{path/to/figure3}}

  subfloat[Caption 4]{label{ref_label4}includegraphics[width=0.5textwidth]{path/to/figure4}}

  caption{label{ref_label_overall}Overall caption}

end{figure}
