Bug#321586: texi2html images licence

(Also replying to bug page & debian-legal (d-l: please CC me on any replies))

Personally from what I have gathered:
 * If texi2html has released the singular images under a special
agreement (from which it seems), then maybe the images should be
released dual-licensed (under GPL & CC), of course under this
agreement Debian would only be able to pickup the GPL part.

Personally, I feel that this could be better:
  * Just use GPL in Debian for these images (solve problem immediately).
  * Work out what programs use texi2html with the images (I do not
believe very many do).
  * In a months time, see for possible re-dual licensing of the images
to fix problems for these packages, or give packages the opportunity
to either not use the images.  (In which I believe is possible)

I'd also like d-legal's opinion on this please.

Not sure if this would be allowed, d-legal may be able to give us a
pointer on it.
