A deep link to my website
I discovered that someone had stolen one of my photographs and put it on their blogsite.
And not only that, it was a deeplink rather than a copy so that every time someone looked at his blog, the picture was downloaded from my home server.
And not only that, he'd use a big picture to download and just shrunk it in his display.
If he's asked, and put up a by-line, I would have gladly let him use the picture of my wife and me in China. Anyway, I sent him an invoice and, true to form, he didn't reply but he did remove the deep link from his blog.
