A Tenant's application and login logos can be managed using the following menu options.
Select the tenant from the table on the Tenant Management page and click the Utils > Upload menu.

The application logo accepts a 30x30 image, and the login logo accepts up to a 200x200 image.
Upload the application logo from your local folder, then click the button to confirm.

The logo has been uploaded and mapped to the tenant, and a confirmation message appears in the top-right corner.

Navigate to Utils > Upload > Login Logo, then repeat the above process for the same tenant.
