Last but not the least, the galleria plugin allows to easily manage galleries of images. Especially, it nicely manages the automatic generation of thumbnails from images, as shown in the following gallery of watercolors due to Pirogh:

When you click on a thumbnail of a picture, a full resolution version of this picture is displayed. Also, try to resize the browser window and observe the responsive display of the gallery: the gallery is automatically readjusted and this is especially useful when displaying on mobile phones. Finally the thumbnail's image resolution itself is also responsive, in the sense that it takes into account the physical resolution of our window and screen resolution. See the source file of this documentation for a complete example and also the documentation of the galleria plugin for more.

To associate an image with an article, i.e. as an icon, add the metadata field. For restructured text .rst files, it writes:

:image: myimage.jpg

to the header of an article. Associated images improve navigation: icons are displayed together with article titles when browsing pages and Archives.
