Figures: Can the list of figures be embedded into the table of contents?

Question

Can the list of figure be embedded in the table of contents for the article class?

I tried a variation of the solution here but by replacing chapter with section and then tried using chapter. The only thing that appeared was the list of figures.

To be more clear, I would like for my figures to be combined with the table of contents not a link to the figure sections; that is, if figure 1 is in section 1, the table of contents will look like

1 something
   figure 1 caption

Figures are setup as

\begin{figure}
\subfloat[]{}
...
\end{figure}

So this is my setup:

\documentclass[11pt]{article}

\usepackage[usenames, dvipsnames, svgnames, table]{xcolor}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{eucal}
\usepackage{pxfonts}

\usepackage{fixltx2e}
%\usepackage[nottoc]{tocbibind}                                                      
\usepackage{tocloft}
\usepackage{subfig}
%\usepackage{thmtools}                                                               
%\usepackage{amsthm}                                                                 
\usepackage{hyperref}
\usepackage[margin = 0.75in]{geometry}
\usepackage{fancyhdr}
\usepackage[caption = false]{subfig}
\usepackage[all]{hypcap}

    \subfloat[\(L_2\)]{\includegraphics[width = 3.25in]{L2Contour}}\\
    \subfloat[\(L_3\)]{\includegraphics[width = 3.25in]{L3Contour}} &
    \subfloat[\(L_4\) and \(L_5\)]{\includegraphics[width = 3.25in]
      {L4L5Contour}}
  \end{tabular}
  \caption[2-D Zero Velocity Surfaces]
  {2-D zero velocity surfaces for the Earth-Moon Lagrange points.}
  \label{fig:2dzerovelocitysurface}
\end{figure}
\end{document}

Answer 1

You change the extension of the file in which figures are written, from the deafult lof to toc; I also used the tocloft package to add the word "Figure" before the number for the entries:

\documentclass{article}
\usepackage{tocloft}
\usepackage{subfig}

\makeatletter
\renewcommand\ext@figure{toc}
\makeatother

\newlength\mylen
\renewcommand\cftfigpresnum{Figure~}
\settowidth\mylen{\bfseries\cftfigpresnum\cftfigaftersnum}
\addtolength\cftfignumwidth{\mylen}

\begin{document}

\tableofcontents
\section{Test Section One}
\begin{figure}[!ht]
A
\caption{test figure}
\end{figure}
\section{Test Section Two}
\begin{figure}[!ht]
A
\caption{another test figure}
\end{figure}
\begin{figure}[!ht]
\subfloat[][A subfigure]{A}
\subfloat[][A subfigure]{B}
\caption{test figure with subfigures}
\end{figure}

\end{document}

Using an empty first argument for \subfloat and reserving the caption for the second optional argument, subfigures won't be listed.

The placement modifier [!ht] was used just for the example; I am not suggesting it should be used in the actual document.

Looking at the preamble added to the question, please notice that you are loading subfig twice: the first time without options and the second one with caption = false and this produces a clash. Load the package only once. Also notice that hyperref must be loaded in last place, just before hypcap.
