Title: image/jpg is an invalid mime type

The valid mime for a jpe?g file is `image/jpeg`, a browser served a file with the mime type of `image/jpg` will ordinarily complain and (I deduce) infer the correct mime type by inspecting the contents. E.g., chrome will issue this warning:

> Resource interpreted as Image but transferred with MIME type image/jpg

It could be interpreted by a reader as a valid alternate mime type just by having this cache-config rule, therefore remove it.
