So I sent them this e-mail:
Hi! This is my photograph. I did let a student use it for a collage, and I guess somebody found it and LOLCatted it (is LOLCat a verb? It is now). I'm OK with that, but I would be tickled if you credited me as the photographer. Thanks! Keera Ann Fox, Norway
Stay tuned! Whoo, got a reply already!
Thx so much for letting us know! We have updated the picture with your name as the photographer. Sorry about the missing credit and great picture! kthxxbai Tofuburger
So now the credit reads: Keera Ann F. That's a new one for me. :-)
