Hi Beverly. I've had several similar requests. The request for HD is because the photos we upload to the this site are optimized for the site and not as high a quality as the originals. The request for what the credit should say is also customary. They usually give credit, by name to the photographer. Often they bye the photo from you. I just sold one for $75 USD. In any case I was very surprised and flattered that my iphone photos would attract this sort of attention. Your photos are all very good. Good camera and good photographer. I hope this was helpful to you.
