Using Server Side Avatars

I am using spark with AD in our corporate environment. Is there a way that I can force avatars that I Set for users and not allow them to modify or change them at all? I want to get photos of each member of the company, and have it displayed next to their name. Obviously, I could do this per station, but then the user could still have the option to change their own avatar. Also, how do I set it up server side to display avatars next to users in the list, not just inconversations?

Yes you need third party software to add the photos to their AD profile on the server. if they are there they will be used and since AD LDAP is read only they will not be changed by users.
