BINGO !!!!! (Sorry for shouting but I'm ecstatic)
It now updates the gif.
my $seconds = time();
# Create graph.
system("/usr/local/bin/graph -L 'Test gif $Ao'
/home/mikel/public_html/tmp/data >|
/home/mikel/public_html/tmp/temp.meta");
system("/usr/local/bin/plot -T gif --bitmap-size 300x300
/home/mikel/public_html/tmp/temp.meta >|
/home/mikel/public_html/tmp/order1.gif");
# Print graph to CGI object.
print $q->img({-expires=>'+30s',
-pragma=>'no-cache',
-cache_control=>'no-cache',
-last_modified=>"$now",
-src=>"http://b4114a/~mikel/tmp/order1.gif?$seconds"});
I've incorportaed it into my molecular modeling program and
that works now as well.
********Thanks to all who contributed the many suggestions

My "HTML Definative Guide" only indicates that the ? is a
search parameter. What does it do in the context of an
image? I'll have to read up on that one.
PS. Matt. If you are at the meeting tonight and going to
dinner I'll buy you a drink.
Thanks.
