I'm new to this so suggestions from those with experience would be appreciated. An airline magazine from Asia has approached me about using one of my images on flickr. They're offering a small sum for each use "if approved" but they need a high rez version to get approval. I uploaded a full size image to my Zen folio site but with a watermark across it. The contact said they can't use it with the watermark because the client has high expectation, what ever that means. Obviously he wants a watermark free full size image. What is industry practice for this situation? If he were to go to a stock site, I don't think he would have access to the images without buying first, correct? Suggestions?
