For a couple of days now msnbot-media is requesting NONE existent JPEGs and GIFs from the site in question. All requests are coming from 199.30.20.* and 199.30.16.* ranges. It started around 11/29/2013 with the first request originating at 11:28:14 PM EST.
The UA that is used is a plain vanilla msnbot-media/1.1 (+http://search.msn.com/msnbot.htm). RDNS points back to msnbot-199-30-16|20-***.search.msn.com.
I own this domain since beginning of 2003. Custom built site by me. All of it. Site is hosted on Dedicated IP, same host same IP from the beginning. PHP is disabled.
The images being requested seem to be a part of WordPress themes, part of the layout and at times some random image names.
So far 468 requests. Examples:

Anyone had observed something like this in the past?
