You probably do not need or want must-revalidate, it's a quite hard
directive. max-age is sufficient I think.

You only need must-revalidate (in addition to max-age) if it's
absolutely forbidden to use the last known version when/if revalidation
should fails to contact the web server for some reason.

You only need s-maxage if you want to assign different cache criterias
to shared caches such as Squid and browsers, for example enabling
browsers to cache the image longer than Squid.

Preferably nothing specific for this since you have control over the web
server..
