This article covers how to add an avatar (a stationary image) for your profile picture in Blackboard Collaborate. Chrome is the preferred browser when using Collaborate.
Note: The process is browser-based and the setting will only take effect for the one browser. If you have multiple browsers (Chrome, Firefox, Safari, and Edge) on a device you'll need to upload your avatar in each browser. The article only pertains to Blackboard Collaborate's environment and not Blackboard's LMS environment.
