This script may be used in place of showmsghdr.js if you already have a

custom msghdr.asc and want to continue to use it (with avatars). Just add
@exec:showmsgavatar@ (uppercase) below your custom header in msghdr.asc.

exec/showmsgavatar.js

+// $Id$
+
+// This can be loaded from text/menu/msghdr.asc via @EXEC:SHOWMSGAVATAR@
+// Don't forget to include or exclude the blank line after if you do
+// (or don't) want a blank line separating message headers and body text
+
+// This script may be used instead of (not in addition to) showmsghdr.js
+// Use this script if you have/want a custom message header defined in
+// msghdr.asc, i.e. with @-codes (not using text.dat strings).
+// If you do not want the avatar right-justified, copy this file to your
+// mods directory and change that parameter below.
