Hello,
Thanks for the question. Unfortunately, we need more information than what you have provided. Are you working in the Builder program? If so, the banner is part of the theme and is only in one location. You can find information on that in our article on uploading a customer banner in the Builder program. If you are using a different program, or coding a banner directly, then you need to provide us more detail. Are you getting an error? Can you have give us your URL so that we can look at the issue? If you wish the issue to be handled privately, then please contact our Technical Support department through chat/phone/email.
I hope that helps to answer your question. If you require further assistance please let us know.
Regards,
Arnel C.
