well trying to replicate this but so far no go http://www.reeftalk.com/gallery/show...1279&nocache=1
There is a photo I edited after adding an additional extra field and I see the prev links. The next previous buttons are all shown based on the query that is given for the next prev options. If your marking photos as mature content they are not going to be shown on that page. That is what I am saying so having alot of mature content is going to surpress alot of navigation.
