Reversing an Inner Join

I have a query that looks like this:

SELECT fname, member.id, filename, friendID,memberFriends.memID, statusID
FROM MEMBER
INNER JOIN memberFiles on member.id = memberfiles.memID
INNER JOIN memberFriends on member.id = memberFriends.friendID
WHERE memberFriends.memID = 19 OR memberFriends.FriendID = 19
AND ID != 19

Basically, it establishes a relationship between two members. It works, returning the "friends" of the member who
s ID is specified. The problem is that when their friend's profile is accessed that member does not show up in the query.

In other words, I need to be able to find all members who friendID matches a memberID, which is the reverse of what this query produces.

Does that make sense?

Please post the table structure for all the tables?
Is the memberFiles table needed to achieve your description for the current query?

I think this does what you want but I may have misunderstood the situation

select m.id, m.fname from memberfrends mf
inner join member m on mf.memid = m.id
where mf.friendid = 27

That query does find what I was asking, but I was looking for a query that produced that result along with the results of my previous query. I think I need to rethink the way this works. Thanks for your help!
