The only problem there is when you group the LEFT JOIN pictures that
have a count of 0 return a count of 1. Unfortunately there's no single
query that I figured out when I did this same project that would give
accurate results.

The problem is that i only get the the pictures that have comments, i
want even the pictures where there arent no comments and the field
num_comments should be 0.
Need a LEFT JOIN
SELECT pics.*, pic_comments.*, count(*) AS num_comments FROM pics LEFT
JOIN pic_comments on pics.id = pic_comments.pic_id WHERE pics.category
= 1 GROUP BY pic_comments.pic_id
