How to add only part name to list of figures

A patch answer by changing \@part a little bit and explicitly adding \addcontentsline with lof instead of toc again.

I have kept the vertical chapter gap in the LoF in order make the elements of figures origination from different chapters more outstanding.

\documentclass{report} \usepackage{xpatch} \makeatletter \xpatchcmd{\@part}{% \markboth{}{}% Find a hook in order to append content. }{% \markboth{}{}% \ifnum\c@secnumdepth>-2\relax \addcontentsline{lof}{part}{\thepart\hspace{1em}#1}% \else \addcontentsline{lof}{part}{#1}% \fi }{\typeout{Success}}{\typeout{Patch failure}} \makeatother \usepackage{hyperref} \begin{document} \tableofcontents \listoffigures \part{Number Three -- the Larch} \chapter{A dummy chapter} \begin{figure} \caption{First figure} \end{figure} \begin{figure} \caption{Second figure} \end{figure} \part{And now for something completely different} \begin{figure} \caption{Third figure} \end{figure} \end{document} 

I adjusted this answer to include the parts and not the chapters in the list of figures:

\documentclass[12pt,a4paper,twoside]{report} \usepackage{etoolbox} \makeatletter \def\thisparttitle{} \def\thispartnumber{} \newtoggle{noFigs} \apptocmd{\@part}{\gdef\thisparttitle{#1}\gdef\thispartnumber{\thepart}\global\toggletrue{noFigs}}{}{} \AtBeginDocument{\AtBeginEnvironment{figure}{% \iftoggle{noFigs}{ \addtocontents{lof}{\protect\contentsline{part}{\protect\numberline{\thispartnumber}{\thisparttitle}}{}{}} \global\togglefalse{noFigs} }{} }} \makeatother \begin{document} \listoffigures \part{A} \chapter{First} \begin{figure}[h] \caption{Caption of first figure} \end{figure} \chapter{Second} \begin{figure}[h] \caption{Caption of second figure} \end{figure} \part{B} \chapter{First} \begin{figure}[h] \caption{Caption of third figure} \end{figure} \chapter{Second} \begin{figure}[h] \caption{Caption of fourth figure} \end{figure} \end{document}
