you really can't imagine that is a copyright infringement, i mean the idea looks the same but there are really different photos it is not copied per se. And what make you think that the original is "original"? If you make a search you will find dozens of photos with the same idea, not only those 2 contributors.

It seems to be easy for making money. I just go to popular page and copy their ideas and adjust it a bit or just make my  photo by copy from them then I can stand in popular page and get more income.

Wowww thanks for good idea
