# Making a caption only label in the table of figures

I am trying to figure out how to make a caption only appear in the List of Figures and not add any space below the figure. I am trying to include two pictures on each page and they are already getting small -- I want to include a list at the beginning of the document, but the added caption is pushing them onto an additional page. Here's an example (I know it's a picture):

The code being used to create this is

    \begin{figure}
\begin{center}
\includegraphics[width=0.9\linewidth]{Graphics/_FullSeries/k100CleanNoLegend.png}
\caption[Full Series $k=100$]{}
\end{center}
\end{figure}


I already know about the trick with the brackets as the list item in the List of Figures and the required argument being blank. I also tried using the caption package with \caption*{}, but then it doesn't appear at all in the List of Figures. Any thoughts?

Thank you!

Try this:

\begin{figure}
\begin{center}
\includegraphics[width=0.9\linewidth]{Graphics/_FullSeries/k100CleanNoLegend.png}
%       \caption[Full Series $k=100$]{}
\addcontentsline{lof}{figure}{Full Series $k=100$}
\end{center}
\end{figure}


which will add Full Series $k=100$ with the page number to the LoF and no caption below the figure (and no numbering); any fragile commands in the Full Series $k=100$ text must be \protected.. Among other places the LaTeX macro \addcontentslineline is described in the tocloft (<texdoc tocloft) package.

But my question is: If there are two or more figures on a page how will the reader know which one is being referred to?
