block google app

[lists at lazygranch.com]

I'm sending 403 responses now, so I screwed up by mistaking the fields
in the logs. I'm going back to lurking mode again with my tail
shamefully between my legs.          

This code in the image location section will block the google app:
------------
if ($http_user_agent ~* (com.google.GoogleMobile)) {
           return 403;
         }
---------
