First of all, make sure that the folder
/var/local/lib/cms/ranking/faces exists. If it does not, then create it with
mkdir /var/local/lib/cms/ranking/faces (most probably you will need to have root access rights to complete this command).
Then, for each contestant (user) you want to assign a photograph, place in the faces folder an image that has the same name as the username of the contestant. For example, if you want to assign a
PNG image to
user admin, then you need to copy the image in the
faces folder using the name
admin.png . Note that the image type can be any of the following
.png, .jpg, .gif and .bmp.
