Has anyone else had this happen to them? I had a D-List celebrity steal one and had a lawyer make them pay up but the US government is a bit of a different beast. I’ve had Cuba and Russia steal it too. I’m not sure it’s worth kicking that hornet nest.
I should probably copyright register it.
I had a couple photos used in some US Gov environmental study PDF’s I found listed online. I release the online versions of my photos licensed under Creative Commons BY-SA-NC. The photos were from Canada but they used them and fully credited me and even left the watermark on the photo.
