Thanks to taker for pointing out this issue, and thanks to Darren for the reply =)
Initially, my paper's "In My Heart" photography competition only decided to award 1st, 2nd and 3rd prizes with Nikon products. But after the judging, our editor felt that there are many more nice photos among the submission, so we decided to publish 10 more photos and award them consolation prizes, which are not Nikon products, but just a goodie bag provided by our marketing department that is not of a very significant amount.
After telling our editor that one of the photos that won the consolation prize also won 6th place in one of Clubsnap's competition, and after the reply from Clubsnap's administrator, we feel that it is okay for the photo to remain as one of our consolation prize winners, and remain on my paper's website =)
