For the second time in as many years I have received an email containing an aggressive claim of an alleged copyright violation. It relates to the use by me of a photograph on my web site. The first accusation of copyright violation came from a woman whom I know. She had emailed the photograph to me. If I recall it was a snap of her (and possibly a companion) rowing on the river. I must have made the mistake of using the photo with my daily blog (and pointedly without having acknowledged whence it came). I accordingly removed the photo from my blog; and, I advised the woman. I haven’t heard from her again.
