I would also vote to delete them.
_Obviously_ we have permission to use _our own_ logos. But our usual
NPOV approach tends to require us not to give ourselves special
treatment. :-)
A solution to this issue might be to enable selective inline linking, so
that an image can be used by providing just a URL, such as:
http://bla.org/myimage.jpg
This is disabled on many (all?) projects (vandalism, external traffic),
but it would be possible to restrict it to our own domain, and to put
non-free content in a restricted space. This could also include the
Creative Commons license logos, which are equally non-free, but used on
all our projects for the license templates.
