Back in 2012/13, a photo that I took at the last concert of the Beach Boys 50th anniversary tour (their final ever with Brian Wilson) was lifted from a Beach Boys forum and used on various external blog and indeed commercial sites.
Now, I don't do photography for money....I do it for fun....but I did write to every site where I found my photo pointing out that I owned the copyright and asking to be credited. A few pulled it, most apologised and credited me. Which was all I wanted. Was rather flattering to have a few more minutes of "fame" though.
I would at least reach out to them and point out that they're using a photo without permission. They might be unaware and could have obtained it from a source passing it off as theirs or public domain.
I do not want to go through every website looking for my photographs, and that is why when one of my photographs on APUG was copied over 250 times in the first 24 hours I stopped posting my work on any website. As a result of that one time, one of my customers cancelled his photograph print order from me. He wanted only photographs that were exclusive to him alone.
