Manual:$wgLogo/de

Details
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. The logo is expected to be 135 x 135 pixels, but this can be increased by modifying the site CSS (and smaller sizes are possible with no changes).

Wenn es ein relativer Pfad ist, muss es mit einem Schrägstrich beginnen (eine Datei im DOCUMENT_ROOT ist /file.png nicht file.png).

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