FORBIDDEN_SET $visibility

[Stramm]

Hi devs, I'm again trying to mod something.. however this time I'm somehow lost cause either I'm to stupid to get it or there's just redundant code... if I just don't get it I'll have some heavy problems with the privacy settings

So after long talking here my lil question... why is this code in index

Code Select Expand

        if ($visibility == '0' || $visibility == (FIRST_USER_CAT + USER_ID) || in_array($visibility, $USER_DATA['groups']) || $USER_DATA['can_see_all_albums'] || $CONFIG['allow_private_albums']==0) {
??
If I don't have private albums... no problem at all... this doesn't change anything.
If I do have them, then in get_private_album_set() FORBIDDEN_SET defines what pics to get from the picture table... and all private stuff that the user isn't allowed to see won't get pulled. So the above mentioned if clause in index is doing nothing at all... ? Or am I wrong here
I've added above each visibility=0 just to check what's happening. So far I couldn't see any drawbacks.´

ahmm.. edit... I'm talking about all 4 occurances of that code
