I know that this is a risk when you post stuff on Das Internetz, but still it's definately unethical. Somewhat optimistically I assume people will play nice and at least ask for permission. Over the years I have had a few people ask to use my photos, and I have sometimes said yes depending on the nature of the intended use. I would be really annoyed if I made a living from my photos, but then I guess I would have unfortunately had to have take steps to make them less accessible.
Proof! The woman who kindly let me know about it, scanned the brochure from the company for me. Low and behold (bottom left), there is my "Coffee & Koigu" pic from last year's Worldwide Knitting In Public Day.
I think I'm going to pursue this further. I'm pissed off for myself, but looking at the brochure (I just posted a snippet here) it is packed full of photos. But just whose photos?
