A slide with the image gallery template can be used to showcase portfolio displays that cycle through images. It is also very useful for scenarios that use case studies as the main focal point.
You can also use multiple images to show a process and the individual steps one would follow. A recommendation as always would be to use high-resolution images as these images usually take up the entire slide.
To create a new slide with a template, click the top left "+ Add" section and then "Create New Slide". From there, you can search and find the template you are looking to use.
