These all have three things in common:

- the MIME type of the image attachment doesn't match the attached image
  file. A rule for trapping that (image type mismatch) was published
  here recently.

- all three have deliberate misspellings on the subject and text body.
  A discussion about this (bad teens) has just ended here.

- one of the Received: headers says 'from unknown', but note that my
  domain host generates this, so its not an infallible mark of spam 
  and should probably be scored low and used only as a component of
  meta rules

Personally, I'd use small to moderate (0.5 - 1.5) scores for rules
matching the first two points, add a meta rule to boost the score of
both these rules fire, and ignore the third point because IME it is not
a spam indicator, but of course ymmv.
