Can cache-control and basic authentication coexist?

I'm looking to speed us the viewing of some large graphics on a small site which uses basic authentication (Apache) controlling access for a small number of users. As the files are static, I can easily use a simple rule like
ExpiresByType image/jpeg "access plus 1 year" - but does anyone have experience regarding cache-control headers and preserving the authentication?

I want the files to be stored in the user cache but don't want intermediate public caches to serve the content without authentication.

Using the cache control type "private" should do the trick, as this one is explicitly designed for signaling intermediate public caches to not store the content.

RFC about cache headers [w3.org] section 14.9.1
