All the images should be the same size with an aspect ratio and quality suitable for fullscreen viewing.
Prepare the images in a Finder folder, select them all and drag them onto the assets list box in the widget settings.
Highlight each image in turn and enter the caption and alt text in the boxes provided.
Set the caption font family, size, color and background color opacity.
If the slider is part of a website designed to be viewed on computers, select "Fullscreen" but leave "Swipe" deselected.
For mobile use, deselect "Fullscreen" and check the box next to "Swipe".
If captions aren't required, uncheck the box next to "Show Captions".
