Well, if your images are being served directly from the file system by
your HTTP / Web Server, you need to look into the server's
configuration.

In Apache, for instance, you can use the mod_expires module to
configure expiry header values, combined with the <filesmatch>
directive to set them for specific files if necessary:

You can do this in either the httpd.conf file or a .htaccess file. 
Providing your hosting solution offers this level of control.  If not,
you're left with finding/writing a routine to stream your image, in
which you can set your response headers.
