Some Homepage Images are self managed and some need to be completed by support programming. If it is a custom page, this would also need to be completed by Support Programming. 

To see if this is self managed, as a Page Manager navigate to:
  1. Pages
  2. Homepage
  3. If you see the Image below
  4. User-added image
  5. Then you more than likely are able to change out your photos. 
  6. If you do not see this you will need to contact Support with the Images you are looking to change and the information of where to change it. Once programming has completed the task we will contact you to have you verify the website.
