When I implement domain mapping, the domain works but some of the images stored in the Media Library don't show. The domain is faraonline.org, but we've had to switch back because of the lack of images. This is a live site so it can't be up without images. You can see what the site should look like at fara.alarmsearch.com. Neither of the two images show. Both are stored in the Media Library as http://fara.alarmsearch.com/files/2011/03/No-false-alarms.jpg and http://fara.alarmsearch.com/files/2011/03/WebSiteFrontPage-Vert-295x336.jpg
When it is mapped to faraonline.org the broken images are:
http://faraonline.org/files/2011/03/No-false-alarms.jpg and http://fara.alarmsearch.com/files/2011/03/WebSiteFrontPage-Vert-295x336.jpg
So one has been "renamed" and one has not. The "re-named" one is broken.
