There are many slide show extensions available for Joomla, as the name of this offering from XML/SWF suggests. And as honest as the name sounds, they have also tried to separate from the pack by including a couple of interesting and less common features.
YASS not only gives users a quick and easy interface for creating a Joomla slide show, it also supports the swipe function in devices that utilize it, such as iPhones and iPads. YASS also includes a download button that is available in the desktop resolution screen size.
Yet Another Simple Slideshow is a free extension available for Joomla 1.5 and 2.5.
For more information see YASS on the JED.
