I took some pictures of the artist Peter Doig's studio in Trinidad last year. I then let Design Week magazine use them in the print version of their magazine on the condition that the pictures were credited and I retained copyright. They didn't pay me but as the writer of the piece is my wife I figured it was fair enough. Now it transpires the pictures are on the Design Week website but without the credit I asked for, and as far as I'm concerned without my permission as I only supplied them for print. Anyway, Peter's work's great so make sure you have a look before the feature, with or without the pictures, disappears under Design Week's subscribers only archive.
