Figure as superscript in section title

Question

I would like to have a section title of special type: I need it to be a letter with a figure in superscript. My code (that does not work) would be:

\documentclass[12pt,a4paper]{article} 
\usepackage[slovak]{babel} 
\usepackage[utf8x]{inputenc} 
\usepackage[T1]{fontenc} 
\usepackage{palatino,verbatim}
\usepackage{amsmath} 
\usepackage{graphicx} 
\usepackage{float}

\begin{document}
\section{$\Sigma_1^{\includegraphics[scale=0.15]{example-image-a}}$}
\end{document}

Is it possible to do this?

otherwise the standard trick of using \section[stuff for the toc, no unprotected fragiles]{actual section heading} will work.... — cmhughes, Apr 25 '14 at 16:08
@cmhughes Can you, please, give some simple example of what you suggested? Thanks. — Suzie, Apr 25 '14 at 16:14
see, for example, amsmath "\substack"-command in section title, Footnote in sub-section title, Using \total of totcount package in section title, and lots more :) — cmhughes, Apr 25 '14 at 16:27

You can either \protect the command from expanding via

\protect\includegraphics[..]{...}

or make it robust using something like etoolbox:

enter image description here

\documentclass{article}
\usepackage{graphicx,etoolbox}
\robustify{\includegraphics}
\begin{document}
\section{$\Sigma_1^{\includegraphics[scale=0.05]{example-image-a}}$}
\end{document}

Thank you, both work very well. Can you, please, explain, what does the \protect command do? – Suzie Apr 25 '14 at 16:09

@Suzie: You should read What is the difference between Fragile and Robust commands? Specific to your case, the argument of \section is considered to be a "moving argument" as it not only winds up in the text where you place it, but also possibly in the ToC. As such, it is written to file where full expansion is attempted unless you \protect (or \robustify) it. Also see David's comment on this topic. – Werner Apr 25 '14 at 16:36
