I'm trying to use an image that ~1200 wide by 100 high, as a StoryMaps Cover image. StoryMaps seems to be resizing the image, based upon some secret minimum Height requirement, and cropping out half of the image on the horizontal.
I've found about 10 places where optimal horizontal dimensions are cited, and claims of optimal resizing, but I can find a word anywhere about vertical dimensions, and this behavior.
Can someone please post the minimum vertical dimension for StoryMap Cover images that will prevent this behavior?
