Zope (--> 'OFS/Image/File/_get_content_type') uses the
"Content-Type" header of the uploaded file (if present).
Otherwise, it tries to guess the content type based on
filename extension, otherwise it defaults
to "application/octed-stream" (if it contains binary data)
or "text/x-unknown-content-type".
