You can't get it to work because you are not thinking the Right Way :-)

A single HTTP request can return an HTML document, *or* it can return
an IMAGE, but it can't do both. [*]

You *could* do something like this, however:

?php
  $_CLEAN['text'] = preg_replace('/[[:alnum:]]/', '', $_REQUEST['text']);
?
html
headtitlerequired by w3c/title/head
body
  pThe text you typed was: ?php echo $_CLEAN['text']?/p
  img src=image_maker.php?text=?php echo
urlencode($_CLEAN['text'])? /
  pThanks you for using our service./p
/body
/html

It seems like your existing solution DOES this already.

There's no way to do it as a single HTTP request, though. [*]


[*] Technically, you *can* embed the image data in the HTTP HTML
output stream, but it's very cludgy, doesn't scale well, usually, and
not supported well by all (ancient) browsers.  Don't do that.

As if should.

Save the image in a temporary location and then send html that  
include and img ... / tag

You don't need to do that.  You can just call the PHP script directly
from the img tag.  Your only problem is how to pass the parameters.  You
obviously can't do a POST request from the img tag, so you either need
to pass the parameters as part of the url as in:

  img src=image.php?text=foosize=10 /

Or you use a cookie-based mechanism like a PHP session and refer to that
from the image.php script.
