Hello, I do not think this is an option anymore. As of May 6, here is the update I saw from the latest release notes:
User Profile Picture and Picture Upload Feature Removed
The ability for users to upload a profile picture on the My Profile – Personal Information page was removed on May 3 and, with the May release, profile pictures that were previous uploaded will no longer appear in the SAP Concur page header or on the user’s profile page when viewed by the user or by a Company Admin.
BUSINESS PURPOSE / CLIENT BENEFIT
This feature was underutilized and the cost of maintaining it was not offset by its value to our clients.
