[htmltmpl] writing directly to stdout while using h::t

[<pk...@ei...>]

vexing issue, pl bear with me.

I am using a module that allows me to create images (think gd).
Typically I write the image to a temp directory, and then include that
image in my html template (see example below)...

.. in the script ..
saveImage($tmpimgname, $tmpimgdir, etc. etc.);
$template->param(myimg => $tmpimgname);
..

.. and then in the template ..
<img src="tmpimgdir/<tmpl_var myimg>">
..

everything works fine. Now here is the problem.

In the saveImage method above, if I use undef instead of the
$tmpimgname, perl writes the image directly to the web server. This is a
great facility because not only do I not have to worry about writing a
cronjob to take out the trash in the $tmgimgdir, it is also
significantly faster because there is no extra write, read to the disk
involved for the image.

Except, while using h::t I can't do this. Or, at least I think I can't
do this because I can't figure out how to have the template see the stdout.

I am shooting in the dark here, and will be posting on the list for the
above mentioned module also. I am posting to this list also... if only
to find out that what I am wanting can't be done... that would be great
to know as well.

Many thanks.
