Status:	Answered	TWiki version:	6.0.0	Perl version:	perl 5.10.1

Hello , I am new to this.I have just installed the twiki but i have never been able to load images .I have searched for it and found out most of the problem with apache conf file. My conf file is :

# Autogenerated httpd.conf file for TWiki.
# Generated at http://twiki.org/cgi-bin/view/TWiki/ApacheConfigGenerator

# We set an environment variable called blockAccess.
#
# Setting a BrowserMatchNoCase to ^$ is important. It prevents TWiki from
# including its own topics as URLs and also prevents other TWikis from
# doing the same. This is important to prevent the most obvious
# Denial of Service attacks.

I have generated this file from TWiki:TWiki.ApacheConfigGenerator but it is not working. Please help me with this.

Discussion and Answer

It looks like your pub alias does not match your directory structure and/or your TWiki configuration. Make sure your twiki pub dir is /opt/twiki/pub as indicated in your twiki.conf file for apache. Then, in TWiki configure match the {PubUrlPath} to the alias, e.g. /pub, and set {PubDir} to /opt/twiki/pub.
