MediaViewer displays images with associated metadata on top of wiki pages. GuidedTour is a framework for creating and displaying interactive tutorials consisting of a set of guider popups.

Create a tour for MediaViewer. Put an "Interactive tour" in the footer to activate the tour. The tour should point out the following features of MediaViewer:

* close button

* metadata panel

* disable/enable

Where applicable, make that feature appear while explaining it in the popup.
