Got it all figured out. Using your commands worked, but I also had to
include -H 'Expect:' due to an issue with lighttpd 1.4.x documented
here - http://redmine.lighttpd.net/issues/1017

Below is what is working for me successfully.

$cat getcamimage.sh
curl -s -S -L -H 'Expect:' -b cookies -c cookies -o loginpage.html
http://10.10.10.191/login.cgi
curl -s -S -L -H 'Expect:' -b cookies -c cookies -o loginresult.html
--form username=ADMIN --form password=PASSSD --form Submit=Login
http://10.10.10.191/login.cgi
wget -q --load-cookies cookies "http://10.10.10.191/snap.jpeg" -O image.jpg

Thank you very very much, Ralph!
