All of my photos (unless otherwise noted) are dual licensed under a Creative Commons Attribution-ShareAlike and a Creative Commons Attribution-NonCommercial-ShareAlike licenses. If you want to use a photo but require a different license (such as the GFDL) contact me and we might be able to work something out.

The reason for dual licensing is the incompatibility between the CC Attribution-ShareAlike and the CC Attribution-NonCommercial-ShareAlike licenses - one cannot make a derivative work using works from both licenses (by-sa derivatives must be licensed under by-sa, by-nc-sa derivatives must be licensed under by-nc-sa).
