When you want to download a picture (from someone else's gallery), you will need to spend points, but the user who owns the gallery gets rewarded for the downloads (by others) with more points. Example 1 : User A, let's call him Alan, likes pictures of girls bending over showing off their asses. Alan could subscribe to a gallery about this very topic. Alan can use his points to download, let's say, 10 pictures from this "ass" gallery, per day.
