how to remove a title from one exact page?

Today I'm asking how can I remove a subsection title, keeping the page number, from an exact page? I've rotated the page and put an image and you can see that it appears '4.4 ALB' over the page. I've tried \pagestyle{plain}\setcounter{25} (25 it's the page), but it didn't work. Actually it deleted from page 24 to 27 (cause it's the end of the chapter). I've tried \thispagestyle but neither this worked. So I hope someone can help me.

\begin{sidewaysfigure}
\includegraphics[scale=0.7,keepaspectratio]{plot/ctree.png}
\end{sidewaysfigure}
\pagestyle{plain}\setcounter{25}


with use landscape environment (because it is not float environment and therefore is simple add \thispagestyle{empty}) instead sidewaysfigure :

\documentclass{article}
\usepackage{afterpage}
\usepackage{graphicx}
\usepackage{lipsum}

\begin{document}
\lipsum[1-2]
\afterpage{\clearpage\thispagestyle{empty}
\begin{landscape}
\begin{figure}
\centering
\includegraphics{example-image}
\caption{my figure}
\label{fig:landscape}
\end{figure}
\end{landscape}
}
\lipsum
\end{document}


• @Bernard can explain me the \lipsum function? I've tried what you wrote putting \lipsum[25-26] (the pages) but it didn't work. Jul 3, 2018 at 19:01
• \lipsum[m-n] gives access to §§ m to n to the Lorem ipsum dummy text (it is a dummy text used by typographers for testing purposes, written i a sort of fake Latin). Maybe you didn't install it? Jul 3, 2018 at 19:06
• @Bernard I saw it writes in latin, but it makes my figures and tables disappear! I don't understand how it should work.. I need only page 25, how can I set it? Jul 3, 2018 at 19:25
• It's not ‘page’, but ‘paragraph’. Simply use \lipsum[25]. Jul 3, 2018 at 19:31
• @SMoini, my document example (called minimal working example: mwe) generate only three page which demonstrate the principle, how it works. it will work also at page 25 of your document. of course, in your document you should remove \lipsum which serve me only to demonstrate my solution.
