Manual:$wgLogo/zh

细节
The URL of the site logo (i.e. the image displayed in the upper-left corner of the page in most MediaWiki installations). Either a fully-qualified URL or a relative path from DOCUMENT_ROOT. Logo应为135 X135像素，但可以通过通过修改站点的CSS来调整大小.

If it's a relative path, it has to start with a slash (a file in DOCUMENT_ROOT is /file.png, not file.png).

Do not simply overwrite the default logo installed with MediaWiki ; this file will automatically be overwritten when you upgrade and your changes will be lost.
