Steve,
When you run from cron you don't have the benefit of your entire
terminal set of environmental variables.
Specifically, you probably don't have the DISPLAY environmental variable
set like you would in your login session- so the gif driver won't
be able to connect to your X display- whcich you need to have
open and allowing the cron user to connect to it. You also should
source the Gemenviron file from your script to specifically
define all those gempak environmental variables that you
have set in your normal interactive environment.
