They don't need to.  Only the person who placed the image on the server 
needs to know that.  If that person doesn't know, you have a problem 
that cannot really be solved by automation.

Browsers are a red herring.  The only reason for modifying browser cache 
  policies is if you want to contradict server policies, e.g. if you 
prefer reducing bandwidth to having the very latest version.  Browser 
manipulation should never be used to implement global policies.
