Ok, a couple of things...
1) You want to move the $r->send_http_header; call up before calling
$template->process();
2) Modify $template->process( $file, $vars, $r) to
$template->process( $file, $vars) since you specify OUTPUT => $r
when you create the Template object (so it's re-dundant).
3) get rid of the $r->print( $output ) line as well, $template->process()
is going to send the output to Apache the way you have it setup.
4) As David Ranney pointed out in a previous post, you might want to
put your images somewhere else, or adjust your URL
You get a path_info part only for the virtual component of your URL
(ie. there's no filesystem component beyond /tt ), but your URL for
images/hello.gif is relative to /tt, which means your handler for
<Location /tt> has got to fix things up.
...or..
If you make the URL hello.gif to resolve to something outside /tt,
then Apache should serve it up as a regular file, which I suspect is
what you want.
