Go to your friends list, then invite them as a friend. If not on your list, do a friend search and then ask them. If they except their picture will be on chat.

some people have their chat disabled because they dont like to chat with other people

but you can just go to their profile and click on "Send a message" (assuming they are on your friends list) and that's the exact same thing as a "chat" on facebook
