documentation licence

[Gorgonite]

Hello


I've already your licence for the documentation.
http://www.freebsd.org/copyright/freebsd-doc-license.html

Unfortunately, I don't understand very well that I can do with it...
I've written for me a more simple documentation about the use of gvinum, and
I would like to put it on my website, with a licence such as the FDL

In this documentation, some pictures are taken from your documentation...
may it cause an issue ?
(Of coursen, I can do other picture myself...)



Thanks.
