Authentication Unique Keys not included

Hi all

I’ve been having gnarly image display problems and getting nowhere.

Now, as I start to consider a fresh install of 2.7 I noticed that the Authentication Unique Keys were never added to the wp-config.php file at install. I just didn’t do that bit!

I’m OK with you all laughing at me if there is a chance that this mistake might be preventing all my images disappearing. Is this likely?

If so, how do I rectify? And with a fresh install, should I clear my database too?
