Hi @Tighe, Debra J. (Contractor)
Currently, there is no option to delete uploaded background images and/or pre-loaded images. The only available workaround so far is to access %APPDATA%\Microsoft\Teams\Backgrounds\Uploads and then delete the file in there. We highly recommend you vote it here in Teams UserVoice. Microsoft will always focus on customer’s feedback and experience, some new features would be added to the services based on customers' feedback in the future, and your good ideas will be very helpful for them to improve the service. Your time, understanding and cooperation will be highly appreciated.
