wp symposium pass avatar to phpfreechat

I want to achive something but i dont know if it is possible. I am developing a website where i want users to be registered and have an account(wp symposium). I also like very much the phpfreechat (wordpress plugin), but it does not have the users photos. From what i’ve seen in wp symposium code is that it recovers the profile picture(and other stuff) with a variable named “$uid”,also i think that the uid var “loads” when the user logs into the site(it looks like a chain reaction). I miss the part where 1)the user logs in 2)uid loads(how???) 3)how to pass uid to another “query” in phpfreechat so that it “echos” the users photo. Thank you all in advance.
