Your analysis of the problem is correct in my case.  Apache and Windows 
XP Pro performed flawlessly with all the latest Windows Updates and 
Norton's Internet Security Pro installed.  All worked very well together 
until I installed ZoneAlarm 5.0 Suite.    There is something inside 
ZoneAlarm 5.0 that breaks Apache from serving images.

Unfortunately in todays world we have to use Windows PCs for 
productivity reasons to build our web applications, in doing so we must 
have a powerful firewall and anti-virus application installed and 
running 24/7.  Norton's was very good until their technical support went 
to Hell, we cannot have any application where we cannot receive 
excellent support, business competition will not allow downtime for lack 
of support.  If ZoneAlarm proves to be in the same category of support 
as Norton's we will be looking elsewhere soon.

While I still have my soapbox to stand on I will shout to the world this 
message; it is support groups like the Apache Group that provide the 
needed solutions for users like myself, without your guidance and 
support we would not be able to exist as a small business.  Thank you 
all for your generous support and time.

Thank you Joshua, for the updated information.
