This is not true. You repeating it will not make it true.

Clearly you either don't know what you mean, or don't know what you're
talking about. Let's be clear: CGI does not have to send HTML! It can
send, for example, a dynamically-generated JPEG, directly to the web
server, which in turn (if the CGI has also sent the proper HTTP headers)
sends it to the client. There's no HTML involved.

All a CGI program needs to return is a valid HTTP header and content.
Sometimes you want a CGI to send text/html; sometimes you don't.

Exactly.

To piss you off. Is it working?

I see. So anybody who doesn't agree with you is a fool. Right.

I'm creating my own spam filter and would like to find software that
can abstract the text from a gif and/or jpg. Any suggestions?

It needs to at least return a proper header.

Why are you complaining about it? If you don't like it then feel free
not to read it.

I know that.

Sorry but I won't.

Again, if you do not send back a valid HTML header the web server (or at
least every web server I've ever used) displays an error complaining
about invalid headers.

Technically CGI is just a protocol - practically you need to return HTML.
