Positioning list in list of figures [duplicate]

Question

Currently my list of figures looks like this
List of Figures Figures 1 ........................x Figures 2.........................x
How to make like this?
List of Figures Figures 1 ........................x Figures 2.........................x
Thank you

My code is:

\documentclass[a4paper,12pt,openleft]{book}
\begin{document}

\tableofcontents
\listoffigures

\chapter{chapter 1}
\begin{figure}[h]
\centering
\includegraphics{images.png}
\caption[Figure~\ref{fig:fig1}]{caption}
\label{fig1}
\end{figure}

\chapter{chapter 2}
\begin{figure}[h]
\centering
\includegraphics{images2.png}
\caption[Figure~\ref{fig:fig2}]{caption2}
\label{fig2}
\end{figure}
\end{document}

Answer 1

If you desire to have no indentation before the entries of the list of figures, you should use tocloft package, and set \cftfigindent to 0pt. See code below.

\documentclass[a4paper,12pt,openleft]{book}
\usepackage{graphicx}
\usepackage{tocloft}
\setlength{\cftfigindent}{0pt}
\begin{document}

\tableofcontents
\listoffigures

\chapter{chapter 1}
\begin{figure}[h]
\centering
\includegraphics{example-image-a}
\caption[Figure~\ref{fig1}]{caption}
\label{fig1}
\end{figure}

\chapter{chapter 2}
\begin{figure}[h]
\centering
\includegraphics{example-image-b}
\caption[Figure~\ref{fig2}]{caption2}
\label{fig2}
\end{figure}
\end{document}

Answer 2

The LOF is formatted by \l@figure which in turn calls \@dottedtocline to add the indentation etc. The figure/caption number is added by \numberline.

\documentclass[a4paper,12pt,openleft]{book}
\usepackage{showframe}% debugging tool

\makeatletter
\renewcommand*{\l@figure}[2]% #1 = \numberline[number}{text}, #2 = page
{\bgroup
  \let\numberline=\@gobble
  \@dottedtocline{1}{0pt}{0pt}{#1}{#2}%
\egroup}
\makeatother

\begin{document}

\tableofcontents
\listoffigures

\chapter{chapter 1}
\begin{figure}[h]
\centering
%\includegraphics{images.png}
\caption[Figure~\thefigure]{caption}
\label{fig1}
\end{figure}

\chapter{chapter 2}
\begin{figure}[h]
\centering
%\includegraphics{images2.png}
\caption[Figure~\thefigure]{caption2}
\label{fig2}
