How do I let buyers switch banner images themselves or change the banner to an automatic slideshow?

1. Find "Manual image switching (show left/right buttons)" in the "Banner" section on the left. 2. When enabled, buyers can use the left/right buttons or dots to switch images. When disabled, the banner runs as an automatic slideshow. 3. Preview the effect on the right, then click "Upload changes" in the upper right when finished.
