SK-Elib

This plugin allows you to customize the logo on the WordPress login screen. There is zero configuration. You just drop the logo file into your theme WordPress and this plugin takes over.

Note that you should use a transparent background on the PNG custom logo, crop it tightly (no padding pixels) and use a width of exactly and min 312 pixels for best results. Wider images will be downscaled in modern browsers, but it isn’t recommended to rely on that.

This plugin also works in the mu-plugins directory.
