Custom Background In MS Teams

UPDATED It looks like this is in the process of being rolled out or at least actively tested.

If you have the version with the option to select a background image, custom images can be added.

Save your image /s in the Uploads folder below

C:\Users\YOUR_USER_NAME_HERE\AppData\Roaming\Microsoft\Teams\Backgrounds\Uploads

Then, in teams while on a call; click the 'More Actions' (Three Dots) at the bottom, select 'Show Background Effects'

The pictures you added should show up on the right hand side of the screen with the default options from Microsoft.

Good Luck!
