FQL with limit do not return results for all users - facebook

Question

Im tryint to get the following query to return results for two of my friends:
SELECT pid, owner
FROM photo
WHERE aid IN (
SELECT aid
FROM album
WHERE owner in (
SELECT uid2
FROM friend
WHERE uid1=me()
LIMIT 0, 2 ) )
But for some reason it does only show result for one of them, and the number of rows returned is not above the limit (only about 800)
When I run:
SELECT uid2
FROM friend
WHERE uid1=me()
LIMIT 0, 2
I get a result with two friends, as expected and when I manually do a query in this form:
SELECT pid, owner
FROM photo
WHERE aid IN (
SELECT aid
FROM album
WHERE owner = USER_ID_FROM_LAST_QUERY
I get the result Id expect for both users, but Why wont it work with the IN-statement and subquery?
Edit: What I try to achieve is to get the photos of all my friends. And just asking for all photos from ALL my friends would be more then 5000 photos, and thus I cant get everything in 1 query.
Currently I got it working by doing a query for each user, to get all his pictures - and it works fine. (if you ignore the fact that it takes 2-3 minutes to execute. So I want to shorten the runtime by doing fewer queries.
Edit: more info:
With the following query i get albums from both users:
SELECT aid, owner
FROM album
WHERE owner in (
SELECT uid2
FROM friend
WHERE uid1=me()
LIMIT 0, 2 )
But with the full query, i only get pictures from albums owned by one of those users.

Answer 1

Try This:
SELECT pid, owner FROM photo WHERE aid IN (SELECT aid FROM album WHERE owner in (SELECT uid2 FROM friend WHERE uid1=me() LIMIT 2 ) )
