Add support for student photo import from an institutional repository. Availability of photos of registered students in a course controlled by course environment parameter: 'internal.studentphoto'. This may be configured to require initial acceptance of conditions of use by course owner. View classlist in ENRL, and Automated Enrollment Manager now includes option to display thumbnails of student photos. Nightly enrollment update can import student photos for students added to a course. Student photos can be updated via the Automated Enrollment Manager.
