If you wish to customize the Webmail banner images that appear on the login page and in the navigation sidebar, you can do so from the Branding page in MDaemon's Remote Administration web interface.
To use your own custom images:
1.Click Use custom images in the Customization section.
2.In the Sign-in Page Image section, use the Choose File or Browse option (depending on your browser) to select the file you wish to upload. This section also lists the default dimension size for each image.
3.Click Upload Custom Image.
4.Repeat steps 2 and 3 for the Sign-in Page Background Image, Navigation Sidebar Image, and Inverted Navigation Sidebar Image.
The uploaded images will appear in their corresponding boxes and now be used instead of Webmail's default images.
