Hello @MarissaG25 ,
You can add to your custom fields and edit current ones through your Contacts (three dots menu) or My Account (Advanced Settings subtab) pages. Regarding your image issue, are you still experiencing it? It sounds like you're running into either a caching error or some kind of interference from a browser extension. I'd suggest some basic connectivity troubleshooting to narrow down the source of or resolve issue. If the issue perpetuates after clearing your cache, or on other browsers, networks, and/or devices, please let us know so we can continue troubleshooting.
