Position of footnotemark after includegraphics

Question

I know a lot of questions have been asked about footnotes in captions and others. I am currently working on a beamer presentation where such mechanism is not always necessary, on the contrary, \footnotes might (I insist on the might) be more relevant there.

I tried to add a \footnote just after an \includegraphics call but the footnote number is placed at the bottom of the picture, which feels kind of weird. I'd prefer the mark to be placed near the top right corner.

It probably is easy to solve, but when searching the internet, I always fall back to the \footnote with \caption related questions.

Here is an example

\documentclass{beamer}
\usepackage{graphicx}
\begin{document}
\begin{frame}
    \includegraphics{example-image-a}\footnote{A footnote for an image without figure}
\end{frame}
\end{document}

Answer 1

\documentclass{beamer}
\usepackage{graphicx}
\begin{document}
\begin{frame}
    \raisebox{-\dimexpr\height-\baselineskip}{\includegraphics{example-image-a}}\footnote{A footnote for an image without figure}
\end{frame}
\end{document}
