How to expose Chinese media's photo-stealing?

Look at the photo above, can you see something interesting on it?

It is known that many Chinese media, including governmental ones, directly use photos downloaded from the internet without paying the copyright or making some statement, and it is worse for these shameless media to print their own logo on the pictures, making it seems that they own the photo. The picture above is a proof, you can see the logo of Global Times, which is a government-owned website and a well-known radical nationalist media, in the lower right corner.

However, this photo of Japanese DDH warship was taken by a Japanese guy, and he is surely a smart guy! He added a secret watermark on the picture using two words which have been definitely forbidden for Chinese media to prove his ownership. If you watch this picture from any side of your computer, i.e., not so directly in front of it, you would see two words "Free Tibet" on the right of the second floor of the warship from below. The two words confirm that this picture must come from outside of China, because no Chinese media dare to print the two words on their own images.

Poor stupid Global Times, they want to cheat the readers, but they have cheated themselves!
