@Dan:
In Power Store 4.5, you can add a similar effect by using a Gallery.
in the power store admin section, go to Content -> Galleries to create a new gallery
After creating the gallery, click the Content menu item and select the content area you want to include the gallery in, such as Home Page -> Site Message and edit it.
in the toolbar, click the gallery button (See attached screenshot) to add the gallery to the content area, select the Slideshow - Wide Gallery type.
