System Settings > Login Screen > Users tab.
By default I believe User Image Source is set to System, I've changed it to User, System. This way if you have an image associated with the login this will show, if no image is associated with the login a default image will load. You can also set the default image in this section. - Jul 20 2012

If this still doesn't work, you can copy the folder in the downloaded file to /usr/share/kde4/apps/kdm/themes/ - this will then appear in SystemSettings as an option to select.
(Note that this is based on Kubuntu 12.04 32-bit - doubt it'll be any different for 64-bit though.) - May 07 2012
