 * When an image is uploaded, it is resized to several registered sizes. Each size
   can have different settings for how to manage images whose aspect does not match
   the defined size. See [https://developer.wordpress.org/reference/functions/add_image_size/](https://developer.wordpress.org/reference/functions/add_image_size/)
 * You can get those black bars when cropping is disallowed and the upload aspect
   does not match the defined size. This is only one of several possible explanations.
   Plugins and themes can alter how uploads are handled and can introduce their 
   own quirks.
 * If you cannot tolerate cropping and cannot tolerate black bars, the only solution
   is to upload images that are already at the correct aspect.
