问题
I am currently using paperclip to upload images to my rails app. This is probably a very simple fix but how or where do I save the missing images to? This is the error that is produced from not having any missing images. How do I change this?
ActionController::RoutingError (No route matches "/photos/normal/missing.png"):

If you don't need any control over the default image, which I don't think you need, you can place it in any folder under RAILS_ROOT/public/images/
Just make sure you point it out in the attachment model with the :default_url parameter. So for example if you place the image in RAILS_ROOT/public/images/normal/missing.png you need t specify the path like this:
has_attached_file :photo, :default_url => "/images/normal/missing.png"
