There is a small confusion in the final sentence of this:
"Slideshow field:

The field that contains the image. Bear in mind that this is a list of all fields, and not all fields will be on each node type, so you must make sure that you have chosen a field that appears on the type of node you're using, otherwise nothing will show up in the slideshow. If you are using a single node type slideshow, this field is expected to contain multiple images. Otherwise, if the field contains multiple images, only the first will be used."

"Otherwise"? If the field only contains 1 image? If if it not a single node type slideshow?
