If you want to use the news editor you need to define some additional Defaults. The paths shown here are these used within the DEB packages, if you use RPM, substitute /usr/lib with /opt.
Defaults write NSGlobalDomain LSNewsImagesUrl '/ArticleImages'
Defaults write NSGlobalDomain LSNewsImagesPath \
         '/usr/lib/opengroupware.org/news'
You also need to add an alias to the Apache config when you are using the Apache Module (Note: the News application does only work together with Apache, it won't work when running the daemon standalone):
Alias /ArticleImages /usr/lib/opengroupware.org/news
Please ensure that 'LSNewsImagesPath' already exists.
(write access for user 'opengroupware' and read access for Apache user)
Simplest add the following line:
umask 003
to ~opengroupware/.profile or ~opengroupware/.bash_profile.
