[[Category:Logo]]
}}
See [[mw:Manual:$wgLogo]]. The logo file for a MediaWiki skin should be 135x135, but other sizes are possible with other skins.
You can upload a file to your wiki, and then use it for the logo by setting <code>$wgLogo</code> in LocalSettings.php
e.g.
<source lang="php">
$wgLogo = $wgScriptPath . '/images/4/47/mylogo.png';
</source>
By accessing the right URL, you can have MediaWiki resize your image for you e.g. <nowiki>https://freephile.org/w/images/thumb/2/29/Freephile_large_logo.gif/177px-Freephile_large_logo.gif</nowiki>
For Meza/QualityBox, just put the logo into the config folder along with other favicon assets.
