[FYI] htdocs/images/images/.htaccess needs mod_headers

Might be of interest if you have a local install of the validator on 
apache2...

The images were not being displayed on the qa-dev server because the 
.htaccess in the images directory requires mod_headers to be enabled.

Quick fix
qa:/etc/apache2/mods-available# cp headers.load ../mods-enabled/
qa:/etc/apache2/mods-available# apache2ctl graceful
