I used the smart look service last week and now my computer desktop will not display my original photo, it is black. How do I change it back?

Welcome to the Community, kbayfilly-yahoo-.

SmartLook is a set of support features designed to provide a more interactive support experience when you're on the phone with our support team. You can check this article for more information: Use SmartLook to share your screen with support agents

Once the Smartlook session ends, the display and controls should be returned to you. If you're having display issues or changes in your background, try rebooting your system to start in a clean slate.

If you're still having display issues or problem navigating inside QuickBooks Online, I recommend contacting our Support Team so that they can create a ticket and investigate it further.

Keep in touch if you require any additional assistance with QuickBooks or its features. The Community is always here to lend a hand. Have a great day!
