When your old photo shows up on marketing pieces instead of your new one it's not your fault. The issue is that your computer cached your old photo.
When your computer "caches" something it does so to try and make your life easier. Your cache will remember emails, passwords, websites, and as you've found out- your agent photo.
In order to get your new photo to populate you will need to clear your cache, log out of Rezora and close your browser entirely.
1.) Clear your cache. This process is totally dependent on what internet browser you are using (Safari, Google Chrome, Internet Explorer, Firefox, etc.). I've found that this website gives helpful instructions on how to do this: http://www.wikihow.com/Clear-Your-Browser's-Cache
2.) Log out of Rezora.
3.) Kill your Internet Browser by closing all windows and tabs.
