Gallery Images seen count

[henne]

Hello,

First:
viewtopic.php?p=477176#p477176
I use pretty much this gallery code and it works, so thanks

Second:
My problem.
I want to count how many images were already seen by the player, so something like:

Code: Select all

default persistent.bg_seen = 0
default persistent.max_bg_seen = #whatever my max will be

##Somewhere in my gallery screen:

"[persistent.bg_seen]/[persistent.max_bg_seen]"

So I was wondering how to achieve that. I know that I would need to add "$ persistent.bg_seen += 1" somewhere but I don't seem to find the right place for it, aside from adding it under every image but that seems a bit awkward?

If something seems unclear please ask as English is not my first language.
