You don't. HTML is a document description language, not a programming
language. It has methods to hook scripting into it, but all the
variable handling must be done in the languges that are hooked not in
the HTML itself.

As far as I'm aware, client side support for PHP is nil.

That would be an example of PHP being used to author an HTML document
on the fly. Since HTML is just a matter of the syntax of the output
format (You should have quotes around the value of the src attribute,
you are missing the required alt attribute, and the filename of the
image is unlikely to be useful advisory information), your question
would be better addressed to a PHP discussion list rather then one for
the discussion of the future design of HTML.
