詳細
An array with factors and their associated relative paths or URL paths to the different versions of the wiki logo. (i.e. the image displayed in the upper-left corner of the page in most MediaWiki installations).

Supported variants
Note that other skins typically require a larger icon if they support this, so using an SVG instead is recommended as it will scale correctly across all of them. This is because the 1.5x and 2x versions assume a nominal width of 135px, and up to 155px tall will fit without issues in standard skins. (so up to 232px tall, for 155px nominal height) (so up to 310px tall, for 155px nominal height)
 * The icon version should be a square and to support New Vector should be nominally 50x50 pixels if SVG, or 100x100 pixels if raster in order to support HiDPI.
 * The 1x version should be 135px wide by up to ~155px tall.
 * The 1.5x version should 202px wide, matching the aspect ratio of the 1x.
 * The 2x version should be 270px wide, matching the aspect ratio of the 1x.
 * The svg version replaces the need for a 1x, 1.5x, and 2x version, but should follow the same nominal size guidelines, fitting within 135px wide and 155px tall when resized to 135px wide.

There are also two optional fields for additional assets to show next to the logo:

Typically this is the graphic version of.
 * The wordmark should be a landscape logo, with maximum set width or height, as these are specified under the  and   keys.
 * The same is true for the tagline, which typically corresponds to the non-sitename part of MediaWiki:Tagline.

All values (except  and  ) can either be a fully-qualified URL or a relative path from DOCUMENT_ROOT. If it's a relative path, it has to start with a slash (a file in DOCUMENT_ROOT is /file.png, not file.png). Instead, the image will be cut off so that only part of it (the upper left-hand corner to be precise) will be visible. If this corner is completely white, it might look like the image would not display although in fact it does.
