First of all, let me apologize for the hacked-up code I sent with my
original post. I was actually trying to return my current code back to
something that looked more like the TT sample code, but I clearly didn't
do a very good job. (In my actual code, I've moved
$r->send_http_header() until after the $template->process() call so that
I can trap file not found errors.)
In any case, thanks to David Ranney. Adding this to my config file does
the trick:
Alias /tt/images /usr/local/apache/tt/html/images
<Location /tt/images>
SetHandler default-handler
</Location>
Thanks.
-Tim
