That was explained, yes. But it was also disputed. I never saw a response to Jim Robinson’s questions in investigating that explanation in this thread.
I answered JimRob in post 1539. The images that had KF instead of EF and 6 instead of O were due to a hastily captured screen image saved as a too lossy jpg on Sunday AM. The best explanation is that someone quite innocently tried to get the Orly images from PDF into a JPG so it could be displayed in the thread (JPG can, PDF can’t). So they did a screen capture of the PDF, saved to file as JPG and linked to the file in the big Sunday thread. Lots of people saw and saved the original image, but the later ones were done more carefully and did not distort the E and the O.
