In the page http://www.knickerbiker.com/products/accessories/ I am able to see one image. It's strange.
Can you please confirm that through FTP you can see the image Untitled-119x90.png at the location wp-content/uploads/2012/10/. If yes, download it to your local machine and see whether you can view the image or not.
I suspect that may be the image are not moved properly or corrupted.
