Gallery Image Scrolling

I am not able to achieve the gallery image automatic scroll like this:

I have used these instructions from the read.me file but no luck. I can use the slideshow function that works but I like the example of how the images scroll in the link above. Thoughts or ideas, please?

# Use the gallery post format

1. Go to Admin > Posts > Add New.
2. Select the “Gallery” post format in the Post Attributes box.
3. Click “Add Media” and upload the images you wish to display in the gallery.
4. Close the Media window and publish/update the post.
5. The images you uploaded should now be displayed in the post gallery.
