In trawling through Flickr, someone has come across one of my photos. They've written to ask if they can use it in a tourist guide, and if so what name they should write for the credit.
On the one hand, flattering. On the other, I wonder how many commercial organisations are using Flickr as a free source of stock photography, relying on the flattering effect of such requests to avoid any reimbursement (like they'd have to pay for stock photography). There would appear to be commercial gain for them in their guide. Nor have they specified print/online/other multiple use possibilities.
What do you think? Would you say yes, if someone approached you about an original photo of yours like this?
