Bizarrely, whilst away, I have had several requests to use, or notifications of use of my flickr photos for various things. It never happened when I was at home. The latest one is a photo from Valencia that has been used in a computer travel guide thingy Schmap. I've added a travel guide picker in the sidebar of the blog (on the right). I think my favourite request has been for a photo to be used in a book about town planning in the Austrian city of Graz. I've never been there.
