meta tag to expire content

Is there a meta tag to expire content so the client will ask the server for images, html etc.?

-- why I'm asking is --

I change my site's logo occasionally, as a joke, and I want my users to see the image on next page request. Image name stays the same -- as does the html. Just the image itself changes (new one overwrites old).

TIA

General usage of "Expires" meta tag:
<META name="Expires" content="Tue, 27 Sep 2005 19:58:02 GMT">
