By default, the banner overlay image is 577px (wide) by 45px (tall). Only the top 35px are visible in UNICOM Intelligence Interviewer - Server Admin; the remaining 10px are clipped by the banner. The recommended size is 577px wide and at least 35px tall. If you upload an image that is not the recommended size, you must create new rules in the .css file to handle it. You can upload the customized image by using the Edit Customer Account dialog. The banner overlay image uses an <img> tag with an ID of IsaBanner1_swoosh. The new image can be any image mime type.
