LDPR binaries in spec

There are a few paragraphs in the current spec ( http://www.w3.org/2012/ldp/hg/ldp.html ) 
which seem to need a bit of clarification, relating to ISSUE-15 probably. I am just noting
it here, as I am thinking about this right now, and noticed these.
It is also related to use cases 4.8 and 4.8.1 of the UCR
 http://www.w3.org/2012/ldp/hg/ldp-ucr.html#uc-manage_media_resources


Definition:
[[
Linked Data Platform Resource (LDPR)
HTTP resource that conforms to the simple lifecycle patterns and conventions in this document.
]]

So presumably resources that can be created in a collection and that get deleted 
when a collection gets deleted. If we add images to a collection, are they then LDPRs?

[[
4.1.3 LDPR servers may host a mixture of LDPRs and non-LDPRs. For example, it is common for LDPR servers to need to host binary or text resources that do not have useful RDF representations.
]]

This seems to suggest that LDPRs cannot be binaries.

[[
 4.2.2 LDPR servers must provide an text/turtle representation of the requested LDPR.
]]

If one were to create a picture, would this say that one MUST return turtle for it by default?
That would not be completely silly it could be a representation of the picture that said
something like:

------------------------------
 @prefix iana: <http://www.iana.org/assignments/relation/> .
 @prefifx foaf <http://xmlns.com/foaf/0.1/> .
 @prefix awol: <http://bblfish.net/work/atom-owl/2006-06-06/#> .

  <> a foaf:Picture;
    foaf:depicts joe, jack, jane;
    iana:alternate <image.jpg>, <image.gif> .

  <image.jpg> awol:type "image/jpeg" .
  <image.gif> awol:type "image/gif" .
--------------------------------

But that still leaves the question what happens if one GETs <image.jpg> 
without an image/* mime type. Does one get a redirect to the previous
metadata file served as Turtle? Or does the server just return the image?

And if one deletes the collection, does <image.jpg> not also get deleted?
