Overview

This module will display a single image from a Media folder.  If there are multiple images in the folder, the module will display a different image each time the page is visited.  This adds variety to the site without creating a complex slideshow.

The module works best when all the images in the folder are resized and cropped to the same size.

You can assign a link to all the images displayed in the module, so that when someone clicks on the image, they will be taken to a specific page on the website.  The link will be the same for all images.

This module is not a substitute for an actual photo gallery or slide show.

Recommended uses are for study abroad pages, or for displaying different images of artwork on the home page of a website.
