\includegraphics and having "." in the image file name

Question

I'm using the graphicx package with

\begin{center}
\makebox[0pt][c]{\includegraphics[scale=0.5]{example2.2}}
\end{center}

to insert images into my LaTeX file.

However, I get an error because of the "." in the image file name "example2.2". If I change it to "example2", then it works fine. Is there any way to use file names with periods in them without getting an error?

no. after . latex search for file name extension (as pdf, png, jpeg ...). — Zarko, Jun 01 '18 at 13:14
@campa You could discern one of the solutions already posted from that question, but it does not directly address this, so I think also having this question is of benefit. — The Pointer, Jun 01 '18 at 13:55
@campa That question is specifically asking about having more than one dot in the image file name; I'm asking about having any dot in the image file name. This question and its answers more directly address the latter. — The Pointer, Jun 01 '18 at 14:01
@ThePointer You are also asking about multiple dots in the file name (the real filename, not what you write in your document) — samcarter_is_at_topanswers.xyz, Jun 01 '18 at 14:03
@campa That's fine. I should have done it earlier, but I totally misread the other question. My apologies. — The Pointer, Jun 01 '18 at 14:08

The grffile package was born mainly for this purpose.

\documentclass{article}
\usepackage{graphicx,grffile}

\begin{document}

\includegraphics{example2.2}

\end{document}

This will probably break all sorts of things, but...

\documentclass{article}
\usepackage{graphicx}
\def\.{.}
\catcode`.\active\def.{\.}
\begin{document}
\includegraphics{example2.2}
\end{document}

No, no, no, no, no. – egreg Jun 01 '18 at 13:32
@egreg --- I thought you might turn up and say that! – Ian Thompson Jun 01 '18 at 13:35

That was the minimal number of no's for the comment to be accepted, but you can add as many as you like. At least don't redefine \.: \catcode`.=\active\edef.{\string.} – egreg Jun 01 '18 at 13:37
@egreg --- I didn't know that \. was defined, so I learned something today. – Ian Thompson Jun 01 '18 at 13:41
