Hi Andreas ,
so this mean also i can't modify the content and view of ( My Profile ) within workspace ?
currently you can only view but not modify your profile as user. As you might know, administering users is currently possible as (Workspace) Administrator, but not as simple user. In addition the "My Profile" does only show attributes on the window that are populated. But, as with the user image, I believe it might be only a missing feature, that will be implemented in future, or so I hope.
But if you like, you can use a simple process e.g. in Request Management, where a user can "request" a modification of his or her data. There you can use some actions to modify the user with the provided data.
