More specifically, Frontpage Slideshow will grab the XL image size from a K2 item if the source image is not present for some reason (e.g. deleted to preserve disk space on hosting accounts with limited storage).
This is a maintenance release.
As a reminder, support for RedShop and Tienda will be removed in the next update of Frontpage Slideshow.
The JoomlaWorks demo site has been updated to use the latest Frontpage Slideshow release. See here: https://demo.joomlaworks.net/frontpage-slideshow [Please keep in mind that he demo site is currently not using a responsive layout]
