# How can I independently number figure pages?

I have a document where all the figures are put on separate pages (sometimes more than one figure to a page, which is fine). This is achieved using the \begin{figure}[p] option in the figure environment. This does exactly what I want and puts any figures always on their own pages.

However, I need these pages to be numbered independently from the main body of text, with a counter for the total number of figure pages. For example, I need the document to progress: page 1, page 2, Figure page 1/3, page 3, Figure page 2/3, Figure page 3/3, page 4, page 5.

I don't mind if the main text page numbers continue counting through the figure pages, but I'd prefer it if they didn't as per my example above.

Thanks.

This isn't quite what you wanted, but you might warm up to it. It moves all the floats to the end of the document.

\documentclass{article}
\usepackage[nofiglist,nomarkers]{endfloat}
\usepackage{lastpage}
\usepackage{mwe}

\makeatletter
\def\ps@float{\ps@plain
\def\@oddfoot{\hfil Float \thepage{ of }\pageref{LastPage}\hfil}%
\let\@evenfoot=\@oddfoot}
\makeatother

\AtBeginDelayedFloats{\pagestyle{float}\setcounter{page}{1}}

\begin{document}

\begin{figure}[p]
\centering
\includegraphics{example-image}
\caption{test}
\end{figure}

\lipsum[1-8]

\end{document}


The only thing I know of that will delay until the float is outputted is \protected@write.

I added two new counters and redefine \thepage as \thetextpage or \thefloatpage as needed, so the \tableofcontents, \listoffigures and \pageref should work.

\documentclass{article}
\usepackage{xcolor}
\usepackage{everypage}
\usepackage{mwe}

\newcounter{textpage}
\newcounter{floatpage}
\renewcommand{\thefloatpage}{{\color{red}\arabic{floatpage}}}

\makeatletter
\newcommand{\floatpage}{\protected@write\@auxout{\let\arabic\relax}% expand at shipout
{\string\newfloatpage{\arabic{page}}}}

\newcommand{\newfloatpage}[1]% #1 = \arabic{page}
{\@ifundefined{floatpage#1}{\expandafter\gdef\csname floatpage#1\endcsname{\relax}}{}}

\newcommand{\mypagestyle}{\@ifundefined{floatpage\arabic{page}}%
{\stepcounter{textpage}\global\let\thepage=\thetextpage}%
{\stepcounter{floatpage}\global\let\thepage=\thefloatpage}}
\makeatother

\begin{document}

\listoffigures
\bigskip

\begin{figure}[p]
\floatpage% place in every figure[p]
\centering
\includegraphics[height=.9\textheight,width=.9\textwidth]{example-image}
\caption{test}
\end{figure}

\lipsum[1-8]

\end{document}
