In postcards.php below <?php insert:define('POSTCARD', 1);
then in includes/functions.php find: $media = $site_template->parse_template("media/".$file_extension);
Replace with: $media = $site_template->parse_template("media/".$file_extension.(defined('POSTCARD') ? 2 : ""));
Then create for each media template alternative template for postcard but in the name add 2
like:
jpeg2.html
gif2.html
png2.html
etc
