Agreed, I don't want to cause anyone else any problems, I do like the idea of a giant turd though. If I photo shopped an image of the Getty building is that infringement or parody? Just kidding.
The less that you say, the better from this point on.
The person that you refer to could have licensed the image from Getty.
All these letters that people want to write aren't always such a good idea.
Let's just hope that a giant turd falls from the sky one day and crushes Getty.
