That's a slight improvement, but there's still a seq scan on pictures:

 HashAggregate  (cost=114.38..114.38 rows=21 width=4) (actual time=7.585..7.605 
rows=21 loops=1)
   ->  Seq Scan on pictures  (cost=0.00..103.70 rows=4270 width=4) (actual 
time=0.015..3.272 rows=4270 loops=1)
 Total runtime: 7.719 ms
