1: If i don’t use one then nothing will display. When i demo the Fat even samples it shows dates (see attachment). Did you actually set a thumbnail for every single date or can the script do this automatically? I haven’t found an option for it.
2: If i do want to use a custom featured image (200×200) when you click on the even it stretches out the image to a wider size.
I want to set a different size image for that but i see no option whatsoever where to do this.
