Yes, as other have already told you...

anyway what I did is this:

http://host/myscript/?p1=1&p2=2&p3=3

myscript produces HTML (Content-Type: text/html) like:

[...]
	<img src="/myscript_image_generator/?p1=1&p2=2&p3=3">
[...]
       
myscript_image_generator does :

 [...]
  $outvars = { $p1 => 1, $p2 => 2, $p3 => 3  } ;
  print "Content-Type: image/png\n\n" ; 

  $template->process('gd_image.tpl',$outvars)
     or die $template->error;

I haven't needed any temporary file otherwise /tmp is the only solution.

Two calls to the web server.
