    \includegraphics[width=.3\textwidth]{example-image-b}
    \caption{Image A from\protect\footnotemark\ and image B from\protect\footnotemark.}
\end{teaserfigure}

    Here's some text\footnote{And a footnote!}

\end{document}

With symbols in the footnotes

\end{teaserfigure}

\maketitle

{
\renewcommand{\thefootnote}{\fnsymbol{footnote}}
\footnotetext[1]{Source for image A}
\footnotetext[2]{Source for image B}
}

Solution 2:

Numbers everywhere

\documentclass[10pt,sigconf]{acmart}

    \includegraphics[width=.3\textwidth]{example-image-b}
    \caption{Image A from\protect\footnotemark\ and image B from\protect\footnotemark.}
\end{teaserfigure}

\maketitle

\footnotetext[1]{Source for image A}
\footnotetext[2]{Source for image B}
\addtocounter{footnote}{2}
