Try this. Just create a dhandler.mp in the folder where the generated
images would be located. You=E2=80=99ll need to change the MIME Type depend=
ing on
the type of image you=E2=80=99re generating.

use Poet qw( $log );

method handle() {
    my $arg =3D $m->request_args();

    # Grab the filename from the path
    # ie. /images/generated.jpg returns 'generated.jpg'
    my $filename =3D $m->path_info();

    # Generate some data
    # my $image data =3D ...
    # ...

    $m->clear_buffer();
    $m->res->content_type( 'image/jpeg' );
    $m->res->header( 'Content-Disposition' =3D> qq{attachment;
filename=3D"$filename"} );
    $m->print( $image_data );
    $m->abort();
}

I hope this helps.
