Placing an image in a fancyhdr

[Bondles]

As the title implies, I'm trying to get one of my header elements to
be an image. Basically, I want the document to do what I expect
\rhead{\includegraphics[width=13pt]{./logo.pdf}}
to do (but obviously, that doesn't work). Any suggestions? Google
searches for all kinds of combinations of latex, header, and image
have been uncharacteristically unhelpful.

\pagestyle{fancy}
\fancyhead{} % Clear all header fields
\fancyhead[C]{\includegraphics[height=13pt]{file}}%
\fancyfoot{} % Clear all footer fields

and it works. By the way, use the If the problem persists, provide a
minimal example that replicates your problem
