I was told the event pictures are 500*222 PNG format but these aren't working

What is the magic number (pixels) and format??

390x173 PNG

Is the Intro picture a different size from the other events as I changed the size to 370x173 PNG and find the same blank slot.



Is it simply no mod can effect the intro picture? Is it hardcoded like the loading screen. I have tried it with name modified as below and also unmodified. When Unmodified I just get the vanilla picture.
