Pay for download

[Stifler]

I wasn´t sure where to put this, but I think it covers alot of grounds so I decided to put it here.

I´m looking for something that makes the whole gallery creditsbased. So you basicly has to earn credits and then give away one credits to be able to download one picture.

So, if you upload a picture and someone downloads it you get 0.3 credits. And if you want to download an image you would need to pay 1 credits.

You can be earning credits by posting on an phpbbforum, uploading pictures and also donate.

Is there something like this out there?
Or would it be impossible to make?

AFAIK there isn't any MOD/PLUGIN for it
You need to code your self or pay someone to do that for you
