The Random Image component is an easy way to add multiple relevant images to a page and have a different 'random' image appear from this list of images each time a user visits a page.
Purpose
The Random Image component can help keep pages dynamic which adds interest for users who frequently visit that page. It could be a suitable component for a page header that displays a different graphic each time.
Best Practice
It is ideal if all images uploaded to this component are of the same dimensions. This will maintain a consistency as users visit and then re-visit a page and gives those with write access to the page confidence that other components on the page won't shift accordingly.
