Personally I'd just install the extension though.. you may find you
want the other things too :)

is what I need to add to the header of each page, as my site has no
images at all except for the logo. I use the latest git version of MediaWiki.
In OutputPage.php we see
function addMeta( $name, $val ) {
array_push( $this->mMetatags, array( $name, $val ) );
But then
http://www.mediawiki.org/wiki/Manual:Hooks/BeforePageDisplay leads to
http://www.mediawiki.org/wiki/ResourceLoader/Migration_guide_for_extension_…
which makes one utterly totally lost. OK, then I found
http://www.mediawiki.org/wiki/Extension:OpenGraphMeta
which of course does exactly what I want... and much more.
But I don't to install any extensions. All I want is to add
that one little line
<meta property="og:image" content="$wgLogo" />
with the $ variable (expanded
like $meta["og:image"] = wfExpandUrl($wgLogo); )
or something. So how do I write the one line hook please?!
