flycatcher, I agree my scenario is not realistic (lot of trolls voting against a picture from the beginnig). In fact I don't really believe it could happen in real ;=) A most serious point could be to completely change the system, just considering the number of votes (it should not be possible to give a note between 1-10, 1 vote = 1). Then divide this number of vote by the number of visitors, thats a counter of visitor appreciation of a pic. That should be very close to my opinion to the n,umber of comments divided by the number of visits. My 2 cent, Yves
