Redirect the users to the homepage when you use an image_id which does not exist

Hello,

I spent more than 4 hours looking in my 4images gallery for the code who redirect the users to the homepage when you use an image_id which does not exist.

For example:

/details.php?image_id=9000000000

First I thought this code do this action:

if (!$image_id) {
    redirect($url);
}

but when I deleted it, I still be redirected to the homepage.


Any Idea?

if (!check_permission("auth_viewcat", $cat_id) || !check_permission("auth_viewimage", $cat_id) || !$image_row) {
  redirect($url);
}
