The site logo variable is used by many contrib modules but the way it is rendered by default leaves little room for customization. Usually it is rendered by the theme in a pre-defined region, linking to the home page and displaying the full image without any possibility of using image styles. Logo Block solves these problems by creating a block that you can put wherever you want, with a configuration form where you can select which page (if any) you want the image to link to, as well as an optional image style that you want to use for the rendering of the logo.

Dependencies
Block (Core)
Image (Core)

Usage
Configure the block at yoursite.com/admin/structure/block/manage/logo_block/logo/configure. Follow the instructions for the link field to optionally add a link and an image style for the logo.
