The ImageSlider extension supports template technology, allowing you to completely customize an extension's appearance and layout.
The look of the ImageSlider extension's default elements can be completely modified by creating a specific template, which defines how an element will be rendered by a client browser. The ImageSlider extension allows you to create templates for the following elements: item, item text, and item thumbnail. You can apply templates for all identical elements within the extension (using extension level templates) or for a particular element (using item level templates).
In this demo, the SetItemTemplateContent property is used to display video files within an extension image area. The SetItemThumbnailTemplateContent property is used to display information about items: text and time.
