Is there a place where the recommended image sizes for the different images are documented?
For example, I tried using a square image (500x500, 1:1) as Featured Image but it did not display well. I tried a rectangular image, but when it was displayed it was cut off from the original size. I want to stop experimenting in each case.
Same things with the thumbnails in the "related events area": if the featured image is wrongly sized, it will not display correctly there.
So...What would be the ideal size (and image ratio) for Featured IMages, Thumbnails, Gallery?
Same thing for other places where images are needed.
