H5P have released an updated to their plugins for Drupal 8, improved Accessibility with conformity to WCAG2.0 and new content types including an Image Slider. Below is H5P’s Image Slider example.
If like me, your library doesn’t update or you can’t use the built-in updater, download the code from Github at https://github.com/falcon-git/h5p-image-slider.
Unzip the file into a folder and rename the folder to H5P.ImageSlider. Re zip the folder and manually upload the file to your Library content.
