Scrolling through photos (next/previous) in a shared folder on mobile

When I share a link to a folder containing photos with others (https://www.dropbox.com/...?dl=0), I want people to be able to view (and optionally also download if they wish) the photos in that folder via dropbox.com in a web browser, whether they have a Dropbox account or not. If they access that link by either clicking or tapping on it directly if they don't have the Dropbox app installed, or copying and pasting the URL into a web browser to bypass their installed Dropbox app, they can see all the photos in that folder. When they click or tap on one of the photos, its preview appears. All good so far.

Now, I want them to be able to scroll through the photos to be able to see the next or previous one while using this viewer in dropbox.com. On a computer, they are able to do this by using the left and right arrows that are made available. But on a mobile device, it doesn't look like the left and right arrows appear. I'm testing this on a a mobile device like my iPhone, and all I can do is close that photo's preview, and choose another photo to preview. In other words, I have to manually open each photo one at a time to view the photos in the folder.

Is there a way to allow natural scrolling through photos in a folder?

Thank you,
Gary
