Parallels Plesk Panel® lets you brand the interface with your own logo. This replaces the default Parallels Plesk Panel logo in the top right corner, which is visible to domain and mail users when they log in to the control panel. You can also make the logo a hyperlink to the website for your company.
To change back to the default Parallels Plesk Panel logo, go back to the Panel Branding Page page, and click Default Logo.
