=== Modes ===
[https://www.mediawiki.org/wiki/Help:Images#Rendering_a_gallery_of_images Gallery modes] will alter the characteristics of the gallery display.
;<code>traditional</code>: is the original gallery type used by MediaWiki.
;<code>nolines</code>: is similar to traditional, but with no border lines.
;<code>packed</code>: causes images to have the same height but different widths, with little space between the images. The rows in this responsive mode organize themselves according to the width of the screen.
;<code>packed-overlay</code>: shows the caption overlaid on the image, in a semi-transparent white box.
;<code>packed-hover</code>: is similar to packed-overlay, but with the caption and box only showing up on hover.
;<code>slideshow</code>: creates a slideshow of the images.
This example is 'packed-hover'
