== Background
To support T373208 some changes are needed in skin code to support display of different images at different screen resolutions
== User story
As a reader visiting the mobile site, it should be clear from the footer that I am on a Wikimedia site powered by MediaWiki
== Requirements
[] The icons in the footer are different depending on the screen resolution on both Vector 2022 and Minerva
[] When I resize the icons in the footer collapse into squares like so:
{F58259287} => {F58259285}
[] The compact icon can be described in $wgFooterIcons
e.g.
```
$wgFooterIcons['poweredby']['mediawiki']['srcset'] = [
"(max-width: 720px)" => "https://en.wikipedia.org/static/images/mobile/mediawiki.png",
];
$wgFooterIcons['copyright']['copyright']['srcset'] = [
"(max-width: 720px)" => "https://en.wikipedia.org/static/images/mobile/wikimedia.png",
];
```
