Document Extension:PageImages support

[ProbablePrime]

The Problem

It was not clear to me that this skin supported Extension:PageImages, a search in the repository revealed just one reference to it and the rest had to be done by digging through the code.

The Solution

Add documentation that details the support for this extension. Similar to: https://github.com/StarCitizenTools/mediawiki-skins-Citizen#search-suggestions

The Alternatives

Continuing to be confused :'(?

Citizen is just using the search endpoint provided by the REST API from MediaWiki by default. The thumbnail in that API can be fed by multiple sources, one being Extension:PageImages. So essentially Citizen is not directly related to Extension:PageImages in any way, as both sides are interfacing with MediaWiki core instead of each other

Agreed, but some documentation here detailing the options would be appreciated.

I will be looking into adding documentation for recommended optional extensions to go with Citizen. For search specifically, it is still a work in progress with a lot of improvements planned, so I am more inclined to wait till it to be stable before adding documentation.
