Caching isn't the only reason the image may be cached not be loaded, the browser might have images disabled, or not support them in the first place.

A meta tag isn't going to do you any good, nor is changing the HTML document - it is the image being cached, not the HTML.

You need to send real HTTP headers along with the image, and you can do that from CGI. The standard text on the subject is the mnot Caching Tutorial.

As for images already cached by the browser - you'll just have to wait until their cache expires and they request it again (and get the new cache control headers). That, or hack around it by changing the URL of the image in the HTML source (adding/changing a query string is a simple way to do that).
