Add Expires Headers for Specific Images

Question

All of the expires headers articles I've looked at give more or less the following solution:

ExpiresByType image/gif A2592000
ExpiresByType image/png A2592000
ExpiresByType image/jpg A2592000
ExpiresByType image/jpeg A2592000

But it doesn't make sense to me because I know which of my images are going to change and which aren't, so I want to be able to add specific expiration dates to specific image files. How would I go about this?

Thanks!

You can use a FilesMatch, eg.

<FilesMatch "\.(js|css)$">
  ExpiresActive on 
  ExpiresDefault "access plus 1 month"
</FilesMatch>

Or for some specific files:

<FilesMatch "^(example.js|sample.css)$">
  ExpiresActive on 
  ExpiresDefault "access plus 1 month"
</FilesMatch>
