Last week I installed w3-cache and moved all the images on http://www.coffeeandvanilla.com to a cdn( maxcdn.coffeeandvanilla.com ).
The problem I'm having is that although the sitemap—generated by yoast wordpress seo plugin—points images to the correct location, google only indexes[sic] images from the category and page site maps but 0 images from the posts sitemap( see screenshot https://dl.dropbox.com/u/4635252/sitemap.png )
This website has been doing quite well with google image-search before the change, visits from google image search have dropped from ~200/day to 11 yesterday
Here is an example entry from the generated posts.xml sitemap http://pastebin.com/vcMRf9VW
Can anyone suggest where the problem lies? My wife(it's her website) is killing me over this, I'm at the end of my tether.
