already when i look at recent posts i see the same variations of 100 posts out of 250 pictures on a page. And this will get only worse with easy generation,
i believe it is important to very strictly enforce uploaders to properly set up and manage parent - child relationship between their posts, because already this site is turning in quite a mess and people would greatly benefit if they would be able to use
ischild:false
because it might be the most needed search function very soon.
