ios camera adds EXIF meta-data to the images.
This data can contain information about image rotation.
But lightbox-react ignores it.
When you try to display vertical photographs, uploaded from ios camera, on some other platforms: linux chrome, android and much more, image is rotated, stretched.
Problem most definitely connected with html img src default behavior: https://stackoverflow.com/questions/24658365/img-tag-displays-wrong-orientation
But in my opinion, plugin should cover those cases.
