Last week I moved all the images on 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? Why have I lost all my google image juice? Should I just wait some more, how long before really worrying?
