Hi,
This normally occurs when we have to concers to the security issue,
so that user don't know where we are having the image, css, js.. Even in the page Source it is completely wrong path will be available . for this just configure apache as below & use the path in the code.

Example :
<img src="http://ip:Port/img/spacer.gif"/>


I[list=1][*]P = 192.168.5.5[*]Port = 90
[*]listen port
[*]NameVirtualHost IP:PORT


<VirtualHost IP:Port>
DocumentRoot /home/www/htdocs/folder
AddType application/x-httpd-php .php
DirectoryIndex index.php index.html
<Directory "/home/www/htdocs/folder">
Options FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
