The purpose of this post is to show how to assign profile pictures to the users of the Contest Management System (http://cms-dev.github.io/ https://github.com/cms-dev/).
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.
