Adding all files in an item to a carousel

I would like to display 4 photos in a carousal on a simple page in an exhibit. All the photos are in a item with the id of 317. Following the manual, I was able to do this: [carousel ids=317] which just shows the first image in thumbnail size. I know that is because the shortcode grabbed the item not files within the item. I could just make and item for each image, but I am only allowed 2 items.

Is there anyway to have carousel to show all images in the item?
