Display problem for inside and outside users on private server

[Xonan]

I have a private web server (apache) on the inside of a firewall. The
firewall has a static IP but no domain name attached to the network. The
server can be reached by using the real IP address and the port number
(8090) that I opened in the firewall, like so...
http://nnn.nnn.nnn.nnn:8090. The server can also be reached from the
inside on the private network by using the servers address...
http://192.168.0.20

So far so good, except in the case of images. If I use <img
src="http://localhost/logo.png" width="417" height="137" border="0"
alt="Logo"> it works fine if accessed from the server itself, but nowhere
else.

<img src="http://192.168.0.20/logo.png" width="417" height="137"
border="0" alt="Logo"> works from itself and on any machine on the inside
private network, but not from outside.

<img src="http://http://nnn.nnn.nnn.nnn:8090/logo.png" width="417"
height="137" border="0" alt="Logo"> works from outside, but image links
are broken for inside users.

I know why it is happening, but so far haven't come up with an answer that
allows images to be presented to both inside and outside users on the
network I have described. A domain name would be a good fix, but is not
an option.

Anybody?

Install php, plug values for domain.

SSI example:
<!--#set var="myserver" value="http://$SERVER_NAME:$SERVER_PORT/" -->
<div>
SSI: <img src="<!--#echo var="myserver"-->logo.png"
width="417" height="137" alt="Logo">
</div>

PHP example:
<?php
$myserver = 'http://'.$_SERVER["SERVER_NAME"].
':'.$_SERVER["SERVER_PORT"].'/'
?>
<div>
PHP: <img src="<?php echo $myserver ?>logo.png"
width="417" height="137" alt="Logo">

A free redirect my be something to look at:

<div>
SSI: <img src="<!--#echo var="myserver"-->logo.png"
width="417" height="137" alt="Logo">
</div>

Ah so. The hosting company that this will eventually be on doesn't allow
PHP but I had forgotten about server side includes. Should do it.

Thanks

Do you have to use absolute URLs? Have you tried:

<img src="/logo.png">

All right, I V, I've seen that x-face somewhere before. It is one of them
generalissimos from the past?

Interesting that you bring that up. It works just fine if that img line
is in a normal HTML script. But if that exact same script is generated
from a CGI program, it does not. Obviously there are some path
ramifications present that I don't understand yet.

So you need to play with the CGI until it spits out the HTML needed.
