The original photo showed up if viewers of the retweets clicked on the trimmed photo, but viewers was not able to see the photographer’s name unless such action was taken, the ruling said. Interesting. This is how Twitter works. On the other hand, it’s also true that it’s technically copyright infringement, since the reproduction is trimmed. I wonder if Twitter has a duty to enforce copyright in both trimmed and untrimmed cases.
