It has only been published in that it was accidentally uploaded to Wikipedia first as a fair use photo-kit image, under the mistaken impression that that was sufficient for it to be used as a profile picture. However, as the individual responsible for taking this picture, I am glad to offer its use under creative commons.

I, the copyright holder of this work, hereby publish it under the following license:
