Uploads a photo for the user which will be displayed on
his/her profile.
This photo will be saved as an
OriginalFile
object with the given
format, and attached to the user's
Experimenter
object via an
FileAnnotation
with
the namespace:
openmicroscopy.org/omero/experimenter/photo
(NSEXPERIMENTERPHOTO).
If such an
OriginalFile
instance
already exists, it will be overwritten. If more than one
photo is present, the oldest version will be modified (i.e.
the highest updateEvent id).
Note: as outlined in
ticket 1794
this photo will be placed in the
user group and
therefore will be visible to everyone on the system.
