How do I change the default logo shown on all my pages?
Click the Manage logo link
The area under the Manage logo link is a live preview of your public pages. Once you have successfully uploaded your new logo it will replace the existing logo in the preview section
Click the Choose file button and select the image to be uploaded
The image to be uploaded must be on your computer already. Images may only be in .png, .gif or .jpg formats and should be no more than 878px wide.
