Similar to the Directory Widget created in and GUISE-131, we need a Gallery Widget. Rather than listing page titles and excerpts, it list media such as images. It may show thumbnails; it may show scaled images in sort of a mosaic; or something between the two with small previews. This first version will use some predefined structure but allow templating in the future.
Undoubtedly the widget will by default use some general semantic structure and rely on styling to produce the layout and any effects.
The widget will utilize certain metadata associated with the media artifacts as appropriate.
