ag 2.3.1 copy to another system, public images not showing

I have two windows XP machines at home with Apache and webs. Regarding Apache configuraion, mysql configuration, drives, etc, they are clones of each other. The intent is to be a primary web server and a backup server.

I switch which server is live by switching ip in the linksys router. Works great. All I have to do is copy all the webs and data files before I switch.

All is working except for the guestbook public images. They work on the system where the user added the entry to the guestbook. When I copy all the guestbook folder/subfolders to the backup system, the images do not display.

The image is in the public folder, and the Java call has it correctly identified.

I even copied the mysql data folder over.

Is there some other pointer or somthing I missed, maybe in mysql db?

Any hints how I can troubleshoot this?

I am spending lots of time on this and have learned the symptom are not quite what I described.
I don't have a good feel for all the failure attributes. The failure is only on Windows 2000 PRO so far. It fails to display the image on Netscape and Explorer.

Windows XP okay.

If I add a guestbook comment with a 100X100 pixel image, it works.

If I add a VGA size image, the image is put in the 'public' folder but does not display. The image box is there, and the javascript iconis there, but no image.
Still testing

A link would help. Are you using something like this. www.my domain name.com/guestbook/ if so try adding index.php at he end.

Okay,
Here is my test system:

You can add or play with it.
