Unable to scroll through photos sent to people via MyCloud url link

I have a WD MyCloud EX4 unit. I emailed a url link to photos from https://files.mycloud.com to family and they are able to view the photos on their PC’s but only one at a time. They don’t have the ability to scroll to the next series of photos…but they have to click on the X on the top right side of the picture (which takes them back to the folder with pictures) and double click on the next photo to view it. I tested this with various browsers and got the same results.

Is there a way to view a series of photos from a MyCloud url link? Maybe the ability to associate the photos with a photo viewer or an ‘arrow’ which one can click on to view the next photo?
