Backend Logo

The backend logo will be modified regarding the environment and the associated configuration. This can be used to e.g. show the current environment in the website logo.

Backend Logo Example

The backend logo will be fetched by the extension configuration of $GLOBALS['TYPO3_CONF_VARS']['EXTENSIONS']['backend']['backendLogo'].

Modifiers

The backend logo modification is identical to the favicon modification. You can use the same modifiers and configuration.
