Referencing a Background Image URL
To specify a background image URL, select from a drop-down list box that is populated by entries in the URL Maintenance table (PeopleTools, Utilities, Administration, Maintain URLs). To reference a background image file on a designated server, add its location to the URL Maintenance table.
You reference a background image in the URL Maintenance table in the same way you would register any other URL.
